The loop has a resistance R. The magnetic field of magnitude B, points into the plane of the paper, and is confined to the rectangular region shown above. Work must be done on the loop at the rate of P, to move it through the magnetic field at constant velocity. Find the magnitude of the emf, & and the current I for the loop.
Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too high

A coil has an area of 100 cm2 with 297 turns connected across a 5.00 Q resistor to form a closed circuit as in the figure. Initially, a 1.8 T uniform magnetic field points upward through the plane of the coil.
