A circular wire loop of radius 15 cm and negligible thickness carries a 2.0-A current
Chapter 26, Problem 72(choose chapter or problem)
A circular wire loop of radius 15 cm and negligible thickness carries a 2.0-A current. Use suitable approximations to find the magnetic field of this loop (a) in the loop plane, 1.0 mm outside the loop, and (b) on the loop axis, 3.0 m from the loop center.
