. In principle, the magnetic field of Earth could be used to generate electricity. At any given position on the surface of Earth, its magnetic field appears very uniform, although is varies in strength from 25 T to 65 T over the entire surface. Imagine that you are going to try to build a generator that is powered by the magnetic field of Earth. You use a Chevy 350 small block engine to turn a coil of wire at 5000 rev min . Assume that the coil of wire is circular with a diameter of 1 m and that the resistance of the wire is 1 .

1. How many loops would be needed to produce a 10 V peak voltage?
