If a magnet is dropped through a copper tubing, the induced current then creates its own magnetic field. What is the direction of the currents magnetic field?
Homework Answers
as the magnet falls it induces a current in the copper pipe.
That current creates a magnetic field that opposes the changing field of the falling magnet, so the magnet is repelled and falls more slowly
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

A bar magnet is oriented above a copper ring, as shown in the figure. The magnet is dropped and passes completely through the ring. As viewed from above, what is the direction of the current induced in the ring after the magnet has completely passed through the ring and is somewhat below it? There is no current in the ring. counterclockwise clockwise

A magnet of mass 0.10 kg is dropped from rest and falls vertically through a 20.0 cm copper tube. Eddy currents are induced, causing the copper to warm up. The speed of the magnet as it emerges from the tube is 1.40 m/s. How much heat energy is dissipated to the environment?

If a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field which exerts a force on the magnet. This force between the magnet and the loop will be repulsive when: A. the magnet enters the loop B. the magnet is halfway through C. the magnet is leaving the loop D. never Please provide an explanation!

Conceptual: A conducting loop of wire is oriented horizontally, and a magnet is falling downward, through the loop. (a) Draw the direction of the induced current that flows in the loop as the magnet falls downward. (b) Sketch and label the magnetic field lines that are created by the induced current in the loop. (c) Does this create an attractive or repulsive force between the loop and magnet?
