2. A coil with N turns is placed into an electromagnet. The magnetic field increases linearly in time, reaching a value of Bo = 0.17 after time t = 10s. Then, it remains constant. The coil has a cross sectional area of A = 100cm², and it is oriented perpendicularly to the magnetic field. (a) What voltage is induced in the coil? (b) Let the coil have a resistance of R=0.52. What is the magnitude of the current in the coil if the ends of the coil are closed? (c) How much energy is dissipated during the switching-on of the magnet? N turns 11.12 B Figure 2: Coil of N turns placed into an electromagnet.
