I tried to make an electromagnet at home but when I connect the two copper wires to a 1.5V battery it keeps short circuiting and heating up. Also it doesn't attract other nails. (lemmy.world)

Without insulation on the wire, the turns are shorted to each other and the nail.

You need your wire to be isolated, and many more turns
