4)A square loop of wire lies in the plane of the page. Adecreasingmagnetic field is directed into the page. The inducedcurrent inthe loop is:
a. counterclockwise
b. clockwise
c. zero
d. depends upon whether or not B is decreasing at aconstantrate
e. clockwise in two of the loop sides and counterclockwise intheother two
5) A vertical bar magnet is moved at constant velocity throughthecenter of a horizontal loop of wire, with its north poleleading.At the instant when the midpoint of the magnet is in theplane ofthe loop, the induced current in the loop, viewed fromabove,is:
a. maximum and clockwise
b. maximum and counterclockwise
c. not maximum but clockwise
d. not maximum but counterclockwise
e. essentially zero
