Not what you're looking for?
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?
