Indicate the direction of the induced current in each of the
situations show bellow, or "none" if there isn't any. You may wish
to make note of your thought process by which you arrive at your
answer in the event that your answer is incorrect such that you
might still receive some partial credit. It may also help to
clarify your answer if you copy each diagram or print the whole
page and draw the direction of the induced current...

8. A bar magnet is dropped through a loop of copper wire as shown. Recall that ou magnet, magnetic field lines point away from a north pole and toward a south p positive direction of the induced current I in the loop is as shown by the arrows on the loop, the variation of I with time as the bar magnet falls through th by which of the following graphs (the time when the midpoint of...
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
your help!
