Question

You decide to build a small generator by rotating a coiled wire inside a static magnetic field of 0.36 T. You construct the apparatus by coiling wire into 55 loops of radius 0.18 m. If the coils rotate at 3.0 revolutions per second and are connected to a device with 100Ω resistance, calculate the average power Paverage supplied to that device.

Pavg = ??? W
