Describe the material each of the item is made of and find the one that is a conductor. That is the ans.

sdfgsdfgs · Answer

No, I am not playing games. Sorry if it sounded that way. I was just trying to help you answer ur question.

The material for an electromagnet needs to be a conductor. So that was why I suggested u to check that.

e.mccormick · Answer

Yes, electromagnets need a conductor.  No way around that.
