    A coil of wire with 40 turns is held stationary between the poles of an electromagnet. The field in the electromagnet is increased from 0 to 0.75T in a time of 225 seconds. What is the magnitude of the induced EMF in the coil if the angle that the plane of the coil makes with the field is 30 degrees?

    The induced EMF depends ...

    Solution Summary

    The solution calculates the induced EMF in the coil as the magnetic field through it changes.
