g A 400 turn circular coil with a radius of 0.3 m is rotated through a quarter turn in 0.417 ms (this corresponds to 60 revolutions per second). Suppose the plane of the loop was initially perpendicular to a uniform magnetic field. If the average induced voltage is 10 kV, what is the magnitude of the magnetic field
