Rare Earth Magnet - Small - Pk.4
Dia 10 x 3mm Thickness Nickel coated. Approx Pull Strength 1.64kg
These magnets feature "rare earth" compounds combined with ferrite (anisotropic) to produce incredibly strong attraction/repulsion. They are encased in nickel jackets because the material itself is very brittle.
We warn you that getting a finger between these could result in a nasty pinch!
