Picked up a lonely T magnet at flea market today. It's pretty weak and I was wondering if there's a wind with wire/pass a current through it way to charge it up. Just for laughs mind you. Not for T use.
Here is a good thread, pretty easy way to do it as most people have this stuff in their garage.
Thanks Seth. One question now that I know it's possible: does the direction of the wire winding make a difference. That is should they both be say clockwise or one c. wise and one anti clock wise? and can a bulb be in series with the wiring instead of the apparent dead short shown? (I seem to remember seeing this centuries ago. Mr.Wizard or some place).
There is the old right hand rule.
Wrap your right hand around one leg of the magnet, with your index finger pointing to the direction of current flow or positive battery terminal and your thumb will point to the north pole.
To charge a Model T Magnet, wrap as many turns as possible around one leg and continue to keep the turns going the same way back down the other leg. Then add some DC voltage to the wire ends.
