7.5x7.5x7.5mm NdFeB Cube Magnets
This 7.5mm neo cube magnet can be used to show magnetic braking-makes an unusual demo. of Lenz Law-Eddy Currents. Click on Details below to see the video.
Click on Specifications below for gauss & pull force at 5 heights above the magnet; the highest readings are always at zero distance with lowest values at 10 & 100mm above.

Watch the video of Magnetic Braking-Lenz's Law/Eddy currents. Note that in the video we actually used a 12.5mm cube in a 3/4" copper pipe but those are harder to find.
Titanium tweezers can be used to handle cube magnets & position them easily. The Mark I Magnaprobe is ultra sensitive & can be used to check stray magnetic fields. The Mark II Magnaprobe is a fast & convenient way to confirm magnet are positioned with their poles pointing correctly.
