5. (6 points) A bar magnetic moves towards a single loop of wire as shown in the figure.
Looking down from above, what direction will the induced current flow as the north pole of
the magnet approaches the loop?
a. Clockwise
b. Counter-Clockwise
c. More information is needed to determine
direction.
6. (6 points) You look at the opening of an ideal solenoid and observe a magnetic field going
into the page with a magnitude of $3.0 \times 10^{-6}$ T. This solenoid has a radius of 0.050 m, and
200 turns-per-unit length. What is the magnitude and direction of the current to produce the
observed magnetic field?
a. 0.0093 A, counter-clockwise
b. 0.012 A, clockwise
c. 0.038 A, counter-clockwise
d. 0.038 A, clockwise
e. 5.0 A, counter-clockwise
