Question
Map sapling leaming ar magnet is dropped vertically through a long piece of copper pipe. Vhat effect does the falling magnet have on the pipe? Select all that apply. The falling magnet... causes the copper pipe to acquire a net charge. causes the copper pipe to produce a magnetic field. has no effect on the copper pipe causes an electric current to flow in the copper pipe. What effect does the presence of the copper pipe have on the magnet? Select all that apply. The copper pipe.. is attracted to and sticks to the magnet. causes the magnet to fall more quickly. has no effect on the magnet. causes the magnet to fall more slowly. Incorrect.Explanation / Answer
The Lenz's Law states that when a current is induced in a conductor, a magnetic field is generated that opposes the action that produces the current. Therefore, the magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly.
Please mark only the last option to check the system answer. Hope this helps
