Question

1. The induced electromotive force in a circular wire loop, with a diameter of 0.3 m, in a region with a decaying magnetic field that is perpendicular to the plane of the wire loop is ___ V. Assume the magnetic field is decaying over 15 seconds from a strength of 0.6 T to 0 T.

2. Calculate the induced electromotive force, in a shrinking circular wire loop, in a region with a magnetic field that is perpendicular to the plane of the wire loop. Assume the magnetic field has a strength of 0.6 T, and, the diameter of the circular wire loop is decreasing over 16 seconds from 0.3 m to 0.1 m. The answer is ___ V.

3. Calculate the induced electromotive force in a circular wire loop, with a diameter of 0.3 m, in a region with a rotating magnetic field. Assume the magnetic field has a strength of 0.6 T, and, the angle with respect to the plane of the wire loop is rotating over 15 seconds from the perpendicular to a parallel direction. The answer is ___ V.
