1. A generator has a rotor consisting of 250 turns. The rotor has the shape of a box with a side length of 20 cm. The stator of the generator is a permanent magnet which can provide a magnetic field of 4 mT. The rotor can rotate at an angular speed of 2.5 rad/s. If at time t = 0 the magnitude of the flux in the rotor is minimum, then the induced emf at 0.4 s is
2.
At what speed must the loop be moved to the right to produce an induction of 250 V if it is known that L = 25 cm and B = 4 T?
