Question

I am trying to figure out a conceptual question and I cannot relate it to any that I have seen before. The situation involves a magnet being dropped through an aluminum pipe with the south end of the magnet facing downward. We discussed a similar situation in class but the north pole of the magnet entered the pipe first.
a. What direction is the magnetic field (flux) to be increased?
(I'm thinking it is downward, because the entire magnetic field of the magnet is still falling)
b. What is the direction of the induced magnetic field?
(I am thinking it is still upward, because the magnetic field of the induced current will still oppose the magnetic field of the magnet)
c. What is the direction of the eddy current?
( I know that I can use the right hand curl rule and curl my fingers in the direction of the induced magnetic field)
d. Does the magnet fall more slowly?
(I assume it does because the two magnetic fields should still oppose each other)
PLEASE EXPLAIN

Explanation / Answer

a) As the magnetic is falling down ward, wether the south pole enters first or north pole , the field due to this increases in the direction of the motion . Hence the flux increases in the direction of the motion i.e., down ward. b) Induced magnetic field will in the opposite direction to oppose the change in the magnetic flux direction .Hence it will be in the up ward direction According to Lenz's law. c) As the induced field is in the upward direction , according to the right hand thumb rule the direction of the eddy currents is in counter clock wise direction . d) Yes the magnet fall more slowly because induced emf opposes the motion of the magnet.
