An e.m.f. Can be induced between the two ends of a straight copper wire when it is moved through a uniform magnetic field.

A metallic loop is placed in a non-uniform steady magnetic field. Will an emf be induced in the loop?

A metallic loop is placed in a non-uniform steady magnetic field. Will an emf be induced in the loop?

Assertion If a loop is placed in a non-uniform (with respect to position) magnetic field, then induced emf is produced in the loop. Reason In a non-uniform magnetic field, magnetic flux passing through the loop will change. Therefore, induced emf is produced.

A semi-circular loop of radius R is placed in a uniform magnetic field as shown. It is pulled with a constant velocity. The induced emf in the loop is
