Question

Explain why plz ? Thank you An ammeter is connected to a coil of wire. A magnet is sitting motionless next to the wire such that its south end is near the coil and perpendicular to the plane of the coil as shown. The meter indicates that a current is flowing through the wire from the left toward the right. What if anything, is wrong with this picture? a) The current should be flowing from the right toward the left. b) The needle should be slanted toward the right. c) The needle should indicate that there is no current flowing. d) There is nothing wrong with the picture.

Explanation / Answer

Option C is the correct answer.

Beacuse, When magnet is at rest, the magnetic flux through coil does not change.

when there is no change in magnetic flux through coil, there will not be induced emf.

so, there should be no current through coil.

Note: Whenever there is a change in magnetic flux through coil, there will be induced emf in the coil. which results induced current in the coil.
