If you were to cut a small permanent bar magnet in half,
a. each piece would in itself be a smaller bar magnet with both north and south poles
b. neither piece would be magnetic
c. one piece would be a magnetic north pole and the othe piece would be a south pole
d. none of these are true

A bar magnet is held stationary while a circular loop of wire is moved toward the magnet at constant velocity at position A as in figure. The loop passes over the magnet at position B and moves away from the magnet at position C. Find the direction of the induced current in the loop using Lenz’s law (a) at position A and (b) at position C. (c) What is the induced current in the loop at position B? Explain.
