Question:

REFERRING TO EXAMPLE 23-8 Suppose the direction of the magnetic field is reversed. Everything else in the system remains the same.

(a) Is the magnetic force exerted on the rod to the right, to the left, or zero? Explain.

(b) Is the direction of the induced current clockwise, counterclockwise, or zero? Explain.

(c) Suppose we now adjust the strength of the magnetic field until the speed of the rod is 2.49 m/s, keeping the force equal to 1.60 N. What is the new magnitude of the magnetic field?
