Homework Statement
I have made an electromagnet out of a 1 ft. iron nail, insulated copper wiring and a 1.5 D cell battery.
My task is to use the electromagnet to repel a small, circular permanent magnet (1 in. dia., 1/4 in. thick)
For some reason, I can only get the electromagnet to attract the permanent magnet. All of my research says that magnets, whether electromagnets or permanent, will attract when opposite poles connect and will repel when same poles connect.
Homework Equations
The Attempt at a Solution
I've done everything I can think of to try and connect the same poles. I've tried flipping around the permanent magnet, connecting the permanent magnet to each end of the electromagnet, and switching the end of the wire connected the negative side of the battery to the positive side and vise versa.
What can I do to make my electromagnet repel the permanent magnet?
Thanks
