Homework Help: Physics

Posted by Valerie on Sunday, March 24, 2013 at 3:01pm.

To construct a solenoid, you wrap insulated wire uniformly around a plastic tube 12 cm in diameter and 45 cm in length. You would like a 2.0-A current to produce a 2.1-kG magnetic field inside your solenoid. What is the total length of wire you will need to meet these specifications? Any help is greatly appreciated. Please let me know how you did this and not just the answer so I can learn how to solve it.
