Materials used
- 1 sphere magnet K-19-C
- 1 sphere magnet K-08-C
- 1 aluminium tube:
500 mm in length, 20 mm in diameter - 1 aluminium tube:
500 mm in length, 15 mm in diameter
Magnetic brake
The drop tube through which the sphere falls down without touching the walls could also be classified as an electromagnetic brake. The smaller the tube diameter, the slower the magnet descents. Using a variety of magnetic sphere sizes and tube diameters is great for didactical demonstrations.
