Help with electromagnet Answered
I have made an attempt to make an electromagnet.
I got a 10 inch iron rod with insulated copper wire wrapped around (see image)
I didnt have enough wire for the whole rod, so the wire is in two seperate sections
I tried a AA 1.5v battery, two AA 1.5v, a 9v, two 9v and a big 6v plugged in both ways (negative, positive).
None seem to work.
I thought it may be the two sections connected together, so i tried all the above batteries again on only one section, and it still didnt work.
Can anyone help me out here ?
