A simple AC generator consists of 20 coils of wire with an area of 1000 cm² and placed in a region where the magnetic field is 0.5 T. What should be the rotational frequency to generate a peak electromotive force of 220 V?
When the current in a toroidal solenoid changes at a rate of0.025 A/s, the magnitude of the induced emf is 12.0 mV. When thecurrent equals 1.50 A, the average flux through each turn of the solenoidis 0.003 Wb. How many turns does the solenoid have?
For a toroidal solenoid, suppose the number of turns is 297, the area is 6.29 cm 2, and the radius is 9.60 cm. The current in the toroidal solenoid increases uniformly from 0 A to 7.32 A in 3.26 us. Find the magnitude of the self-induced emf.
