The earth's magnetic field at one location in the magnet ospherehigh above the earth's atmosphere is 3.0*10-7 T. Acoilwhose inside area is 5000m2 rotates in the magnet osphere so that the flux varies from the maximum possible value to the minimum possible value in 1.2s. How many turns must the coil haveto develop an average induced emf of 120V for use by a nearby space platform?
