Question

Question 2 1.5 pts 2) A circular coil with a radius of 0.2 meters wrapped 44 times is spun at a frequency of 34 Hz in a uniform magnetic field to form a generator. It is then connected to the primary transformer. The primary side has 36 turns and the secondary side has 18 turns. The maximum secondary current is 8 amps and the resistance of the coil on the primary side is 3 Ohms. What is the amount of the magnetic field in the generator in milli-Tesla?
