Eclipse Neodymium Magnet 5kg, Length 11.5mm, Width 22mm

Threaded Neck Pot Magnets

These rubber-covered neodymium (NdFeB) pot magnets from Eclipse Magnets offer strong holding force that resists corrosion and protects against surface damage.
These neodymium magnets are recommended for use with painted or varnished articles, or applications where a strong magnetic force is required, without scratching or marking.
The rubber coating protects the magnet even in humid conditions where corrosion is more likely. Even after years of use the holding force is not weakened.
