May sound funny but in grade school I made a magnetizer. I remember using a 
toilet paper roll wrapped in shielded copper wire, a baby food jar, a couple 
of small bolts and a electical cord.  I figured I could find out something on 
this by searching but I have found absolutely nothing.  Granted this was 40 
some odd years ago but it was fun and I am sure that I made my father mad by 
magnetizing a bunch of his screwdrivers.  Does anyone know how to do this, I 
thought it would be a good project for my daugther.  Thanks for your help.
