Joule Thief question

[revs]

I am gonna build a small joule thief to pull the life out of some AA, AAA, C and D alkys. I want to make the power wires to the thief have magnets on the ends so I can just stick them to whatever size cell I have. Question is, where can I find a magnet with a wire lead? I know that if I try to solder a lead onto a magnet, it will lose its magnetism. Any other suggestions? Maybe some Arctic Silver or something and epoxy the lead to the magnet?

Thanks guys.

Why will it lose the magnetivity? The heat from soldering?

You could always use conductive epoxy.

Thats what I was wondering. Thank you datiLED. And, from what I have read, yes the heat from a soldering iron will make a rare earth magnet lose its magnetism.

I will try the epoxy.

Where can I get some of this conductive epoxy?
