Homework Help: physics EM

Posted by Spencer on Monday, March 31, 2008 at 10:31am.

You have a 0.600-m-long copper wire. You want to make an N-turn current loop that generates a 1.30 mT magnetic field at the center when the current is 0.600 A. You must use the entire wire.

What will be the diameter of your coil?
this doesnt seem that hard but I cant figure what I need to use.
