Question

If you drop a copper tube over a bar magnet with its north pole up, is a current induced in the copper tube? If so, in what direction? Consider when the copper tube is approaching the bar magnet.

a) Yes, clockwise.

b) Yes, counterclockwise.

c) No, there is no induced current.

d) The direction depends on the length of the copper tube.

Answer 1

Yes, the induced current will be produced in the clockwise direction when viewed from above.

Step-by-step explanation:

The answer is a) Yes, the induced current will be produced in the clockwise direction when viewed from above. Yes, the induced current will be produced in the clockwise direction when viewed from above.

When a copper tube is dropped over a bar magnet with its north pole up, a current is induced in the copper tube. This phenomenon is known as electromagnetic induction.

According to Lenz's law, the direction of the induced current creates a magnetic field that opposes the change in magnetic flux. In this case, as the north pole of the bar magnet approaches the copper tube, the induced current flows in a clockwise direction when viewed from above.
