An AC generator is to have a maximum output of 332 V. Each coil has an area of 0.146 m² and a resistance of 16.6 2 and rotates in a magnetic field of 0.725 T with a frequency of 37.2 Hz, with the axis of rotation perpendicular to the direction of the magnetic field. (a) How many turns of wire should the coil have to produce the desired emf? N = turns (b) Find the maximum current induced in the coil.

A loop of wire has a self-inductance of 5.5 mH.  You pass a current of 9.0 Amps though the loop, and then drop the current to 0 at a contastant rate over 3.5 seconds. What is the EMF generated?

Use the worked example above to help you solve this problem. An AC generator consists of eight turns of wire, each having area A = 0.0890 m², with a total resistance of 10.3. The loop rotates in a magnetic field of 0.445 T at a constant frequency of 63.5 Hz. (a) Find the maximum induced emf. V (b) What is the maximum induced current?
