$65.(8$ points$)$: A bar magnet is aligned along the axis of a loop of wire $($the dashed line$).$ Initially,

the magnet and the loop are not moving. Then, the loop starts to rotate around the axis. The

rotation is clockwise when viewed from the magnet side. Describe the induced current in the loop

when viewed from the magnet side?

$($a$)$ There will be a clockwise current as the rotation starts, dropping to zero when it reaches a

constant speed.

$($b$)$ There will be a constant clockwise current.

$($c$)$ There will be a counterclockwise current as the rotation starts, dropping to zero when it

reaches a constant speed.

$($d$)$ There will be a constant counterclockwise current.

$($e$)$ There will be no current.
