Directions: Answer each problem on a separate sheet of paper. 1. A stationary coil is in a magnetic field 2. that is changing with time. Does the emf induced in the coil depend on the actual values of the magnetic field? 3. A copper ring and a wooden ring of the same dimensions are placed in magnetic fields so that there is the same change in magnetic flux through them. Compare the induced electric fields and currents in the rings. In Faraday's experiments, what would be the advantage of using coils with many turns? 4. Discuss the factors determining the induced emf in a closed loop of wire.
