Faraday’s law states that the induced emf in a coil is directly proportional to the(1 Point)rate of change in the magnetic field.rate of change in the magnetic flux.rate of change in the electric field.rate of change in the electric flux.

Analyze how changes in the velocity of the conducting loop in a generator affect the magnitudeof induced emf

When a loop of wire is rotated between the poles of a magnet, the induced emf can be generated. Which of following DOES NOT influence the induced emf ?(1 Point)the magnetic field of pole.the length of wire.the cross sectional area of the loop.the rotating speed of the loop.

A conducting loop of radius 10π√cm is placed perpendicular to a uniform magnetic field of 0.5T. The magnetic field is decreased to zero in 0.5s at a steady rate. The induced emf in the circular loop at 0.25s is:

1. A wire of length 1.0m moves with a speed of 10m/s perpendicular to a magnetic field. If the emf induced in the wire is 1.0V, the magnitude of the magnetic field is
