A closed loop of wire is being moved so that it remains in a uniform magnetic field. The current induced in the coil is

Answer 1

The current induced in the coil:

1. A closed-loop of wire is being moved so that it remains in a uniform magnetic field.
2. Because when the loop remains in the field the magnetic field remains constant.

On the basis of a uniform magnetic field:

1. It has the same magnitude.
2. It has also the same direction throughout the region under consideration.
3. So the field lines need to be both parallels.

A diagram to represent the uniform magnetic field:

A formula of the uniform magnetic field:

$F=qvB\sin \theta$
