Question
A bar magnet is dropped from above and falls through the loop of wire shown below. The North pole of the bar magnet points downward as it falls. Select the correct option for each statement:
Options: increasing, decreasing, no change
a) increasingdecreasingno change The change in flux through the loop as the magnet enters the loop.
b) increasingdecreasingno change The change in flux through the loop as the magnet exits the loop.
Options: upwards, downwards, no force
c) upwardsdownwardsno force The force on the bar magnet as it exits the loop.
d) upwardsdownwardsno force The force on the bar magnet as it enters the loop.
Options: up, down, left, right
e) updownleftright The direction of the dipole moment of the loop as the magnet enters the loop. If the loop is approximated to be a magnet, this would be direction of the vector pointing from the South pole to the North pole of the loop.
f) updownleftright The direction of the dipole moment of the loop as the magnet exits the loop. If the loop is approximated to be a magnet, this would be direction of the vector pointing from the South pole to the North pole of the loop.
