Question

Sapling Learning A bar magnet is dropped vertically through a long piece of copper pipe. What effect does the falling magnet have on the pipe? Select all that apply. The falling magnet... causes an electric cument to flow in the copper pipe. causes the copper pipe to produce a magnetic feld. causes the copper pipe to acquire a net charge. has no effect on the copper pipe. What effect does the presence of the copper pipe have on the magnet? Select all that apply. The copper pipe... has no effect on the magnet. causes the magnet to fall more quickly. is attracted to and sticks to the magnet. causes the magnet to fall more slowly. about us careers partners privacy policy terms of use contact us help

Explanation / Answer

a) The falling magnet will produce variable magnetic flux across the pipe (increasing) which will lead to the production of a magnetic field in the pipe itself to oppose the cause according to the Lenz's Law.

b) Magnetic field produced tries to oppose the increasing flux by repelling the falling magnet and hence slowing it down.
