Which of the following will cause an induced current in a coil of wire?
Which of the following will cause an induced current in a coil of wire?
| the constant field of the earth passing through the coil | |
| a magnet resting near the coil | |
| a magnet being moved into or out of the coil | |
| a wire carrying a constant current near the coil |
Homework Answers
a magnet being moved into or out of the coil will cause an induced current in a coil of wire because it'll result in change in flux
To have induced current, there should be a change in magnetic flux. In the given options, only C can produce a change in magnetic flux concerning the coil.
Options A, B, D have flux, but they are not changing with time. Only a variable magnetic flux induces a current.

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!

A flashlight can be made that is powered by the induced current from a magnet moving through a coil of wire. The coil and magnet are inside a plastic tube that can be shaken causing the magnet to move back and forth through the coil. Assume the magnet has a maximum field strength of 0.05 T. Assume that the radius of the coil is 1.5 cm and the magnet is shaken with a frequency of about two shakes per second....
