Your old Magneto will need this! How to build and use a electro-Magnetizer! 

I too have had engines that I have turned over more times by hand than it has turned when running! This might well be worth a try, and I have the scrap laying around to build one, Thanks!! Number of turns of wire(about)? Gage of wire used? Approx diameter of rods?

Very good video Richard!!! What you cover is almost lost knowledge these days. I've got to make one of those chargers now! Thank you!

Great video, building a magnetizer has been on my list of things to do for quite a while.

Its been some time my friend since you posted any video's .hope all is well with you!.....see you soon I hope

I was already having a great day, and this video made it even better. One of my favourite channels, without a doubt. Many thanks. 🇬🇧👍

Gday, I’ve always wondered how to make a magnetiser, great results, thanks for sharing, cheers

Thank you for sharing you magnetizer build and test with us. What a cool video!

I think even Michael Faraday would be proud of that magnetic monster! Have you seen his original electromagnet at the Royal Institution? I've seen magnetos where people have stuck neodymium magnets onto the poles in an effort to boost the magnetic field. Now, when I was still in school, which is a long time ago, we were taught to place a keeper across the ends of the poles. The purpose of which is to complete the magnetic circuit, which in turn would preserve the magnetic field density - a couple of large bolts, or a piece of steel bar would suffice. Once replaced into the magneto, the pole pieces and the rotor were sufficient to maintain the circuit. The rule of thumb was never to leave magnets without a keeper in place.

Very interesting. Too bad I didn't have this information back in 1958 when I had an old Cushman motor scooter with a magneto that was hard to start.

Add a diode across each coil, to avoid sparking at the switch so much. The collapsing field is making a voltage spike, a backward diode will short out the back EMF, problem solved.

The magnetizer works great! Always glad to see a new video from you.

Amazing, Richard. Outstanding old-school knowledge for an interested, pleasant young man who is ready to share it with others. And now, pleeeease, show us how to re-magnetize a magnet-flywheel from an old motorcycle or stationary engine. I am going to travel to Sweden this summer. Hope to meet you there. Hälsningar från Tyskland.

Alternate title: they just don't make them like they use too

Cool. Now if and when I ever need need too regenerize a magnet I know almost kbow how.

Hi Richard, at first thanks for this Video. would you please tell us some dimensions as diameter of wire, how many windings, the lengh and diameter of the core. Thanks a lot. Henning

Is this your first flux capacitor?

Nicely done. Since you are using an old and powerless battery the current through the magnet is mainly determined by the current source capability of the battery, not the wire resistance. Given the spark on your switch when you disconnect the current, the current is really low. You are using thick and heavy wire but you have plenty of space around your cores. You if you would double the number of windings, the current would remain more or less the same, but the magnetic field would almost double as well. If it also makes your magneto magnet stronger is determined whether the cores of your magnet become saturated, and when the magnet itself is saturated. Measuring the saturation of your magnet could be done by measuring the field and note when it does not increase anymore when the current or winding count increase. If that would be of interest at all. In any case, saturation of the cores do not harm the functionality or the quality of the field.

Thanks for demonstrating this process. It is what I consider to be a good solution to a problem: simple yet very effective. At any rate, It reminds me of when I used to work for a company that used a lot of magnets in their products. The "magnets" arrived from the manufacturer in the unmagnetized state (I don't know what you call a magnet before it has been magnetized, I suppose there is a word for that.). The reason they came this way is that unmagnetized magnets are much easier and safer to handle and can be more easily machined if necessary. So, we had a device called a "magnet charger" which was used to magnetize the unmagnetized magnets. You put the unmagnetized magnet in the machine, pushed the button, something inside the machine went "click", and instantly the magnet became a full fledged, fully magnetized magnet. Just like that. I always thought it was kind of magical.

Actually it is better to shorten the magnet poles by means of a steel bar. You recommend to keep it far from steel (15:00). But the contrary is true. Magnets loose their force when a reverse magnetic field is working onto the poles. By putting a steel bar over the magnet poles, the magnetic circuit is closed again an less susceptible to external magnetic fields. Even if you put the magnet on a steel table, the table acts as a shorting bar. An almost infinitely large bar, but it still closes the magnetic circuit.

Havent seen anything new for a while......any problems? I shure do not hope so!!! I love yor little Clips!!!

Awesome to see you back at the videos. This was truly informative and hope you continue to create these learning videos in the future.. Thank you !!

Richard, I really enjoy the videos. I have a magnetizer built by Allen and it has several steel blocks with different angles that lay on top of the magnet charger poles for charging round magnets in flywheels and armature magnets. Keep up the good work!

Please put a real contactor instead steel Blade tò close the circuito. Youll obtain a higher curarent tò give a higher magnetic field

Try heating it with a blowtorch just before or while tapping it. It will significantly increase how much magnetism it take and how long it will hold it for in the future. Do not cool it rapidly in water though. Cheer and thanks for the video.

C'mon Rich! The harvest season is over. Time to get some steam punk, badass videos on youtube that your known for! Love you always, Burton Reingold

Thank you for another interesting video.

Richard, what happened to you! Been looking forward to another video.

That old 2-stroke is amazing! What was it used for?

Great video thanks, but I would change those old HT leads.

Well Done. It is amazing how much you increased the magnetic force of the magnet by remagnetizing it. I believe tapping the magnet with the brass “hammer” assists the repositioning of the field/pole molecules in the magnet. Thanks for another interesting and informative vlog.

Hur många varv koppartråd lindade du? Grovlek på kabeln? Bra och informativ video

I wish you were somewhere I kould apprentice with you. What about the true dc magnetos that you kould attach a lead anywhere to the block and it would fire 1 to 12 cyclinders without a distributor?

Nu vill ja bara bygga magneten för de såg så kul ut. 😁. Snyggt jobbat!

Are these magnets just soft iron? It doesn't look like alnico.

Hi and thanks for that,could you please draw a basic wiring diagram,including which way around you wind each coil and hoe each end is connected to what…thanks.

Richard, have you seen the cast iron curiosities channel? Its things like this.

Thank you! This is by far the most simple and easy to understand video on magnetizers I have seen. I'm ready to build one for my own shop.

The thicker top steel pieces might not be creating the effect you intend. It will result in a weaker but more even (parallel) magnetic field than a thin piece. Consider tapering one end of the pieces so that you can rotate them to create a more concentrated field when needed. Also consider slotting the top piece mounting hole to minimize the air gap.

Your videos are getting better and better as you are gaining confidence in front of a camera

Very enjoyable! Thanks for posting.

Great little video, Richard. Loved the DYI magnetizer and the explanation. Looks like it was a bit cold inside the workshop. All the best to you. Cheers.

Awesome information that is one cool machine, thank you for sharing

Erik Lehnsherr most likely won't need this tutorial.

That’s a great idea!!! Great job!!!

Hello... You haven't posted in a few months.... Is everything okay? I look forward to new videos

A great device Thank you for the Video Take care yours Frank Galetzka

As usual Richard, a very interesting and informative video, thoroughly engrossing! 👌👏

Hej, I love magnetos and was just thinking about this. It's been a while since I've seen your video. I so want to see your shop if I can get to Sweden again. Do you ever have anyone stop by?

mycke intressant video

Great episode, some great information about remagnetising mags. 👍😎

Very good, thank you. Take the little truck for a road trip in Spring?

Hi, thank you for being nice to me! Hope i didn't run you off and discourage you from making new videos. Im sorry for my stupid texts. Don't pay my stupid texted any attention and keep making awesome viddos! You my favorite person on youtube and watching your videos makes me happy! Burton

This is a brilliant video. I have many pieces of equipment that I have sold because I could not get the Magneto to work. If I had realized it was possible to repair the magnets I would have done so long ago. Thank you so much for sharing this

Very smart man enjoy your vid.

cool man!

Thanks Richard Absolutely interesting 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

Ingenious, Mr. Richard !

I have magneto bsa motorcycle, can used this method without take out magnet inside magneto? Just put casing ?

What have you been doing Rich? Nothings more steam punk than your vids!

Didn't know. Thanks 👍

Excellent video. Very helpful. Thanks!

Always interesting to learn about old things 😎👍

Jättekul att se dina filmer igen! Det ser ut att vara kul hemma hos dig med alla gamla maskiner 😃

Looking forward to you're next video😊

This video is great. The only problem is making the electro magnet

Were is your country dear ?

ALWAYS INTERESTED IN THE OLD IRON. ANOTHER GREAT VIDEO, THANKS FROM OVERLAND PARK KANSAS U.S.A.

How do you remagnetise a flywheel magneto? I have a wheel horse tractor with no magnetism in the flywheel

That was very informative.

Brass is not necessary. In fact the harder the impact like with a high carbon steel small hammer is best.

Very informative thank you

Awesome work, Richard. Thanks a lot for yours videos. I hope you are OK. All of us are waiting for yours new project.

It’s a cool motor like to see it working thanks for sharing

We had a mag remagnatised , but I never knew how they did it , thanks

Great vid Stay well

🫀You genius. Keeping history alive . 🇬🇧🧐🥇❤️

Such a simple solution to a real issue around these old Magneto units. Great build as well using safe voltages that almost anyone can do.

Is that a wasted spark type magneto?

Maybe next time in town pick up a couple of spark plug wires. Otherwise it was a very good video and useful thanks

Excellent, the magnet is a key part of the mag and often completely ignored. 👍👍

👍👌👏 2) Thanks a lot for making teaching explaining recording editing uploading and sharing. Best regards, luck and especially health to all of you.

You have shown a hole lot of people how to build a very inexpensive magneto changer.l love your Chanel and wish that you made more videos. Keep up the amazing work.

3:50 - The baseplate is made of prefamulated amulite

How much layers of wires do you have on the magnet?

hello,congratulations for video.well explained,excellent light.bye-bye

Always feels like a video from the 1940's - excellent content!

Iama recient subscriber. I need to make one of those magnitizers! I enjoy your videos. My great grandfather Charles Thorn came from Sweden in the late 1800's

I like your videos! Keep up the good work!!! I'm curious about that 2-cylinder engine - do the pistons come up and go down together, or does one come up before the other? Judging from the sound, I'd say they come up one after the other. This would make the engine fire one and then the other, with a longer time before they fire again.

I've cranked this thing more than it's ran on its own, that was funny! Thanks!

Very nice demonstration 👍👍🇺🇸

The channel just gains one more subscribers from Brazil.

Is that an "impulse" magneto? (One that will fire regardless of how slowly it turns.)

Very cool!

Ooooh I like so much you share this kind of knowledge quite lost today. Thank you!! ⭐️

Another great video, I have always wondered how the re-magnetizing was done. Greetings from the province of Manitoba in the centre of Canada.

Wakey Wakey electrons

What a great informative film thankyou. I have a ransomes mg6 crawler which i could never get started until i closed the plug gap right up and now i know why. Many thanks from Australia.

Thanks for sharing bro.....🙏🙏🙏

Reminds me of an old, slightly unsafe trick to get more powerful magnetisation that acts really quickly so you don't need to spend time tapping on it etc. Instead of that springy switch you made, wire in a piece of aluminium foil maybe half an inch wide and a couple inches long. And instead of the 12V battery, a standard plug for 240V AC. When you plug it in, the alu foil acts as a fuse and burns away almost instantly. What makes this work is that the foil will never break while the AC sine wave is passing through zero volts heading towards the opposite polarity, it always fails near the top (or bottom, opposite polarity) of the alternating sine wave where the voltage is highest. So instead of a mere 12V through the coils, for 1/50th of a second you have 240V or thereabouts and then the alu foil burns away to break the circuit. It never gets around to alternating to the opposite polarity because the circuit is broken by then. And the coils never overheat despite the high current, because they're only energized for a brief moment. The downside, of course, is you get random polarity with a 50/50 chance of your magnet being the wrong way around. A sufficiently powerful diode could fix that, I guess. Now obviously this trick predates OHSA by several decades; don't actually try this if you don't want to risk electric arcs burning things and splattering melted aluminium everywhere.

How about farm implements, like hay drag rake, two furrow Bamford plough, sickle mower.
