As a new electrical engineer for the local power company, you are assigned the project of designing a generator of sinusoidal ac voltage with a maximum voltage of 120 V. Besides plenty of wire. you have two strong magnets that can produce a constant uniform magnetic field or 1.5 T over a square area of 10.0 cm on a side when they are 12.0 cm apart. The basic design should consist of a square coil turning in the uniform magnetic field. To have an acceptable coil resistance, the coil can have an most 400 loops. What is the minimum rotation rate (in rpm) of the coil so it will produce the required voltage?
