B µ I 2 R FARADAY`S LAW and THE AC GENERATOR
... A large fraction of the electrical power used by the world today is obtained by converting the rotational energy of a turbine into electrical energy. This is usually done by having the turbine turn a coil of wire inside a region where there is a strong magnetic field. The production of an electric c ...

EDI Exam III problems
... 9. Consider two equal point charges q, separated by a distance 2a. Construct the plane equidistant from the two charges. By integrating Maxwell’s stress tensor over this plane, determine the force of one charge on the other. Do the same for charges that are opposite in sign. 10. A charged parallel-p ...
