Neodymium Disc Magnet - 20mm x 3mm | N42 | Epoxy Coating

This rare earth disc has a diameter of 20mm and a height of 3mm. It has a magnetic flux reading of 1810 Gauss and a pull force of 4.3kg. It is identified by the AMF magnet part number 20018A. Uses for our rare earth disc magnets:

The Epoxy Coating prevents damage to both the magnet and the surface it is attached to. This coating also protects the magnet and the surface it is attached to from corrosion or magnetic degradation that results from exposure to the weather.They can be used alongside other plastic material to disguise their presence and invoke a sense of mystery or magical power. These coated disc magnets are a practical choice for outdoor use.

The N42 Grade of magnetism compensates for the weaker adhesive power caused by the coatings intrusion between two surfaces.
