hey folks, i'm working on this project and i'm interested in creating my own magnets. i know to do so i have to heat up the neodymium beyond its curie point(310 - 400 C).

what i would like to know, is if i connect the metal to a circuit, so it acts as a resistor, and pass a high enough current through it, will it reach the temperatures i want it to? and if so, what kind of currents do you think would be required?

 

What is the metal resistance?

 

I'm going to assume that your material is bar stock. The amount of current that you would need to heat this to 300 deg. would be astronomical. Better to put your bar stock on the barbie.

Well, perhaps. However, you can get pipe thawing transformers that can crank out several hundred amps quite readily.

Not in my neck of the woods!

Ahh...I supposed perhaps not! Well, your next choice would be a machine shop that has a spot or resistance welder.
