What if instead, the field decreased as 0.82e-3t T over 0.1 s, now what is the induced emf? Also which way does the ENC go?The generator in the figure uses a loop that rotates with a period T. Suppose the rotation rate (i.e. frequency) is increased so that the loop is made to rotate twice as fast. How will that affect the magnitude of the induced emf? Area - A J Horseshoe magnet N The magnitude of the induced emf will increase by a factor of two.
