A circular coil enclosing an area of 100 cm2 is made of200 turns of copper wire. The wire making up the coil hasresistance of 5.0 Ω, and the ends of the wire are connectedto form a closed circuit. Initially, a 1.1-T uniform magneticfield points perpendicularly upward through the plane of thecoil. The direction of the field then reverses so that the finalmagnetic field has a magnitude of 1.1 T and points downwardthrough the coil. If the time required for the field to reversedirections is 0.10 s, what is the average current in the coilduring that time?

Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.
