A bar magnet is dropped with a vertical copper tube and also is observed to fall exceptionally progressively, despite the fact that mechanical friction between the magnet and also the tube is negligible. Which of adhering to ideal explains the factor for this?
A. The falling magnet magnetizes the copper pipe which reasons the now long-term copper pipe magnet to tempt the falling magnet for this reason causing the slower descent.
You are watching: If you drop a bar magnet in a vertical copper pipe it will fall slowly because
B. The falling magnet is slowed by the Earth’s magnetic area.
C. The changing flux of the falling magnet induces a magnetic field in the copper pipe, in the opposite direction of the bar magnet's area, which impedes the motion via the pipe.
D. Friction and Air resistance reason the magnet to fall a lot slower than it would certainly external of the tube.
