1) A square loop of wire lies in the plane of the page. A decreasing magnetic field is directed into the page. The induced current in the loop is:
a. counterclockwise
b. clockwise
c. zero
d. depends upon whether or not B is decreasing at a constantrate
e. clockwise in two of the loop sides and counterclockwise in the other two

2) A vertical bar magnet is moved at constant velocity through thecenter of a horizontal loop of wire, with its north pole leading.At the instant when the midpoint of the magnet is in the plane ofthe loop, the induced current in the loop, viewed from above,is:
a. maximum and clockwise
b. maximum and counterclockwise
c. not maximum but clockwise
d. not maximum but counterclockwise
e. essentially zero
