To practice Tactics Box 25.1
Using Lenz's law. Lenz's law is a useful rule for determining the
direction of the induced current in a loop. Specifically, it says
that there is an induced current in a closed conducting loop if and
only if the magnetic flux through the loop is changing. The
direction of the induced current is such that the induced magnetic
field opposes the change in the flux. The following Tactics Box
summarizes the essential steps in using...

For direction questions the choices are:
into page, out of page, clockwise, counterclockwise, or no induced
field. Letters (m), (n), (q) and (r) have choices: up, down, left,
right, into page, out of page, or no induced field. The change in
flux is either increasing, decreasing, or constant. Thank you for
