m txnu4j+h2mh*53x sgs. The speed of each coil is given, and the dimensions can be seen from the grid.
Which statement(s) are correct about the instant when the loops enter the magnetic field?
I. The magnitude of induced emf in the coil K equals the emf in coil M.
II. The magnitude of induced emf in coil M equals the emf coil N.
III. The induced current in coil K is in the opposite direction to the induced current in coil L.
