A student drops a strong magnet down a long vertical copper tube. The magnet does not touch the sides of the tube.
The magnet takes much longer to fall through the copper tube than through a plastic tube of the same size.
Explain why the magnet falls more slowly through the copper tube.
After falling a short distance through the copper tube, the magnet falls at a constant speed.
Explain why.
