Size for sizeNeodymium Magnets are the most powerful magnets to be developed; also referred to as Earth Magnets. They may be used for many magnetic demonstrations where intense field strength is an important criterion. For example; if a neodymium magnet is dropped down a length of copper plumbing pipe; the eddy currents generated in the copper by the passage of the magnet create a retarding field great enough to measurably increase the time of fall of the magnet.
Alternative sizes are also available (B8R08026 - 4mm x 10mm; B8A47132 - 10mm x 10mm)
WARNING:
- Supervision required when using strong earth magnets.
- Harmful if swallowed.
