Building a magnet-magnetizer

[jean]

I've got a old electro therapy machine from 1850. It is a simple
horse-shoe magnet with 2 coils rotating in front of it. But the magnet is
weakend after 153 year. I want to build a magnet-magnetizer. Can somebody
help me with tips suggestions or mabye even plans.

Thanks

Jean

Wind many turns of insulated wire around the magnet. Say 100 or so.
Connect one end of the wire to the negative terminal of a car battery.
Connect the other end of the wire for one second to the positive end of the
battery.

For a small outlay this site in the UK has plans for a remagnetiser.
