There are 2 concentric loops of wire which lay flat on the pageand share a center. They are both single turn loops. For theouter loop, r=24cm and has clockwise current I=2.0A. For the innerloop, r=5cm. The magnetic field at the center of both loops is 0.Find the direction and magnitude of current for the insideloop.
Please show the formula and solution. A diagram would behelpful too.
