How does temperature affect the strength of an electromagnet???
 
I have 5 iron bolts and I put one in the freezer for 24 hrs., put one in the refrigerator for 24 hrs., keep one in room tempereture, put one in boiling water for 20 min., and bake the last one in a 350 degree oven for 20 min.

If I use each one as a core for an electromagnet, which bolt do you think would affect the electromagnet so it would be stronger?

My hypothesis is that the higher the temperature, the stronger the electromagnet will be, so I would say the bolt in the oven. Do you think this is right???
