Question

A single horizontal loop of wire is moving in a horizontal plane ata constant speed across a uniform vertical magnetic field that"fills" and surrounds the loop. The emf induced in the loop will be

A)time varying.
B)greater than zero (positive).
C)either greater or smaller than zero, butconstant.
D)none of the above. Hint: Even though the loop is moving, the magnetic flux through theloop is not changing. The field is constant and the loop keepsits orientation with respect to the field.

Hint: Even though the loop is moving, the magnetic flux through theloop is not changing. The field is constant and the loop keepsits orientation with respect to the field.

Explanation / Answer

(D) none of theabove . The emf induced is proportional to the rate of change of themagnetic flux. The flux does not change... so the induced emf willbe ZERO.
