HOMEMADE MAGNETO CHARGER 

I was told by a old timer to charge the magnet on the mag. He sed it makes a big difference in the charge. Any time u pull the magnet or Armature out it can lose magnesium he sed to always do them as a whole unit when you can. He use to work on these 80 years ago

actually a bigger battery wouldnt change much. The current I= 12V/R where R is proportional to the length of the wire windings. That battery is plenty. Probably should add a capacitor to that system.

This is a tool that should just be passed around form shop to shop. Its rarely ever used but when its needed its really needed.

and now all your guys credit cards don't work . lol

I know electricity makes magnetism, and magnetism makes electricity. I don't know why, but this is a great demonstration of it! Liked a lot:)

Turn the lights off to see the spark

How many turns on each coil? Do you remember?

Instead of using a lawn mower battery, why not just plug it into the wall?

Why doesn't anyone show how to wire up the magnets to achieve the desired polarity ?

That is a strong electromagnet! Every time you energized it my hair stood on edge clear over here in SW Minnesota!

I just love this pair, don't know exactly why but I do.

Good job guys. I made one years ago for the mag off an oilpull tractor. it was pretty much the same as yours.I charged the magnets enough that I used it for years before they needed recharging again.

Great video I like your set up

Fantastic video guys.

Interesting video, Mike is a smart guy.

Such a simple little rig .. But it sure makes a big diff in the magnets strength !!

You guys always have something interesting going on!

Cool vid... that Mike is a sharp fellow!

You can use a portable welding machine to power up at higher amps

That was some cool stuff to see !!!
