Question

A circular loop of wire with a radius of 5.0 cm carries a current of 1.0 A. Another circular loop of wire is con-centric with (that is, has a common center with) the first and has a radius of 10 cm. The magnetic field at the center of the loops is double what the field would be from the first one alone, but oppositely directed. What is the current in the second loop?
