Sure, just try
to accumulate static electricity
on a piece of metal
by rubbing it. It will not work.
But even if you could, it would be worthless: what you want is to magnet
ize it, not to charge
it ... two very different things, since charging
is about an excess (or a lack) of electrons, while magnetizing
is about magnetic orientation of domains.
Anyway, to give a positive side to this WU, you can magnetize a metal bar by holding it in a fixed north/south orientation and hitting it with a hammer.
