Pulsars, or neutron stars, rotate at a fairly high speed, and they are surrounded by strong magnetic fields. The material in neutron stars is a good conductor, and hence a motional emf is induced between the center of the neutron star and the rim. Suppose that a neutron star of radius 12 km rotates at the rate of 35 rev/s and that the magnetic field has a strength of 1.00 x 10" T. What is the emf induced between the center of the star and a point on its equator
