A circular coil of wire 3.89 cm in diameter has a resistance of4.71 Ω. It is located in a magnetic field of 0.58 T directed at right angles to the plane of the coil. The coil is removed from the field in 0.235 s.
1. How much electric energy is lost in the process?
2. What is the induced emf in the coil? Suppose the magnetic flux is reduced linearly.
