In this video I show you how it is possible to have a permanent magnet that turns on and off with the flip of a switch. I show you several ways that a magnetic field can be blocked.

I have seen this "switchable" magnet system on a portable drill press which uses magnets to attach itself to whatever steel item you are drilling, in my case, a large "I"beam. I was intrigued by the way it could be switched on or off just by turning a dial on the side, and now I know how it is done thanks to you!😉👍

@johninni4844
@johninni4844 Год назад
old drill bases use a different method ..... There is another way to do this , old Machine shop magnetic bases use a round magnetic inside of steel cube with 1/4 inch of non ferrous brass separating the two Steel sides.. When the north -south poles of the magnetic are aligned n the brass the magnetic field / flux completes the path shunting the the magnet = Off condition . Switch On by rotating so north-south poles are aligned to the steel . The NIB magnet ( Neodymium ) design seen in the video has a more powerful holding force than the the old base but old Machine shop magnetic bases are still sold so must be cheaper.

A variant I've seen on stationary machines is alternating brass and steel plates, and the magnets slide to align under the steel (to engage) or brass (to release).

You can also suppress a permanent magnet using Lenz’s law, by coiling a wire around it in much the same way you would make an electromagnet but in reverse. Once you apply a current to the coil when arranged correctly it will suppress the permanent magnet with an equal and opposite electromagnetic polar force. We use this principle in railway engineering. You should give it a try :)

When welding frames, you can use a magnetic square that has a mechanical switch on it, once the magnet is "on", the square is able to stick to metal pretty easily, when flipping the switch "off", it interacts with some mechanical components that move the magnets inside the square away from the inner walls of the square, moving them as closely inwards as it can

@cisarvialpando7412
@cisarvialpando7412 3 года назад
They are done by powerful solenoids....the piece of metal that has to be magnetized is place inside the solenoid and very large amount of current is passed through the solenoid which in turn creates a strong magetic field around that metal and that metal becomes a permanent magnet.
@1boobtube
@1boobtube 3 года назад
Screwdrivers just rub it on a strong magnet or leave a small neo magnet stuck to it. It wont be that magnetic but will hold a screw. Real magnetizing fixtures use solid copper gold plated buss bars a truck battery size capacitor bank and I assume large transformer? to develop a quick massive current to the fixture. RUD can happen and blow the heads off the bolts if it's not done correctly. Not sure about the transformer but the capacitor bank is big enough to need wheels. Putting a pre magnetized pc in a fixture needs to be oriented correctly or you just made a missile.

@schwig44 3 года назад
look at places like mscdirect or mcmaster-carr, they have bases for indicators used in machining that have used this tech since the 1920's, and they are much better designed to be useful as a magmount for things rather than as a pickup tool like the one in the video... for less than $40 you could get this part number from mcmaster 20715A44, and it even comes with the indicator ( a crappy one, but you want the base) you could prob use it to mount cameras and such edit: I just looked back at the product page, the thing can hold 132 pounds if that matters at all, lol

Wow, that's awesome! I wonder if there could be a mechanical application for this to power a small vehicle. Through a complex system, maybe many of these devices could be synchronized to activate at certain points of a rotation, providing rotational force to an axle. Maybe the machine could even be hand cranked!

I remember a couple years ago I was playing with some magnets I had and figured out that they have values; that they’ll cancel each other out if one is facing north and one is facing south. And now I’m realizing, I pretty much did figure out how to turn off magnets. I feel so smart.

K&J Magnetics is a great source for all sorts of magnets like this. NOTE: be very careful letting magnets snap together! Neodymium is extremely brittle and fractures easily creating some pretty sharp edges and teeny fragments that stick to things and are a pain to clean up (usually I mash duct tape onto the magnetic "gravel" and that does the trick).

I have often wondered if magnets could be paired with mechanical linkages to produce perpetual motion. Then I remember friction. Could a friction less mechanical linkage be possible ? Maybe those magnets that levitate ? Liquid bearings ? Is there some energy source that we have not discovered yet that will overcome E=MC squared ?

so by angling magnetic poles 180 degrees you can “turn off” the magnetic field. so wouldn’t it make sense to be able to amplify the magnetic field by alining magnets so their poles are at right angles to each other?
@MakutaNazo

Yup. Particle accelerators do this along the entire ring of the accelerator. Though, the magnetic field in this case is less responsible for accelerating the particles and is more like a gutter guard in a bowling alley.
@peterboneg

I assume that it takes energy to turn the magnetic switch on and off to overcome the magnetic resistance to rotating one of the magnets. Otherwise you could use it to make a perpetual motion machine (A kind of motor that used permanent magnets instead of electromagnets).

Electric generators used to run around 30% efficiency. Put a coil of wire in the magnetic field and the force to move the magnet to change the field will vary with the energy drawn from the coil. Maybe not that simple but no free energy.

all you videos are so good! i am intrigued by magnetics i have had a love for them since i was 8 years old and my dad brought some home one day. mostly i thought about making a motor that runs itself using magnets. i found 2 ways to do it but then i saw a real ufo it was a 5 foot diameter ball it glowed like the moon with what looked to be a orange gas inside where the light was coming from and it only made a small hum sound. it hovered off the roof of our house then it went diagonally down just off the ground a few feet and hovered in a half circle into our street it went about 50 feet straight level and then changed its angle to about 45 degrees and accelerated non stop faster until it was out of sight in under 4 seconds and it left a streak of light at the end as it went out of sight. so now NASA says we can make a warp bubble motor to achieve lightspeed and i was wanting to see if you could try to explain how they would make one? or make a small model to help us understand better. thanks for all the science its awesome!
