A bar magnet is dropped through a upright copper tube and also is observed to fall an extremely slowly, regardless of the fact that mechanically friction in between the magnet and also the pipe is negligible. Which that following ideal explains the factor for this?
A. The fallout’s magnet magnetizes the copper pipeline which causes the now permanent copper pipe magnet to attract the falling magnet therefore causing the slow descent.
You are watching: If you drop a bar magnet in a vertical copper pipe it will fall slowly because
B. The fallout’s magnet is slowed by the Earth’s magnetic field.
C. The an altering flux of the fall magnet induces a magnetic field in the copper pipe, in the opposite direction that the bar magnet's field, i m sorry impedes the activity through the pipe.
D. Friction and also Air resistance reason the magnet to loss much slower than it would exterior of the tube.
