A loop with 10 turns and radius of 0.4 m is placed perpendicularly in a uniform magnetic field. A 40 V electromotive force is induced in the loop. After 10 s the radius of the loop is decreased to 0.2 m. Calculate the (a) initial area of the loop.
(b)new area of the loop when it is decreased.
(c) magnitude of the magnetic field.

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
