Question

The figure shows six situations in which a loop of wire is near a long, straight wire. In each case, the figure shows whether the current in the straight wire is constant, increasing, or decreasing. If the loop of wire is moving, it is moving in the direction indicated and with a constant velocity.

(a) In which of the situations, if any, is the magnetic flux through the loopdecreasing?

(b) In which of the situations, if any, is the magnetic flux through the loop constant?

(c) In which of the situations, if any, will there be a current induced in the loop goingclockwise?

(d) In which situations, if any, will there beNOcurrent induced in the loop?
