What Are Adhesive Magnets Used For?

The atomic number of neodymium (chemical symbol Nd) in the periodic table is 60. It is a rare earth metal and one of the Lanthanides series. When added to Iron (Fe) and Boron (B)， the resultant adhesive magnets are the strongest magnets currently available.

Neodymium magnet is sometimes known as Neo, or NIB magnets. NdFeB magnet mainly composed of neodymium iron and boron is the third generation of rare-earth permanent magnets. Sintered NdFeB is the strongest permanent magnet in the world up to date.

Advantages and Applications of the Adhesive Magnets

They have the advantages of high magnetic remanence, coercive force, and magnetic energy products. They can be manufactured in all kinds of shapes and sizes and are widely used in electric appliances, medical apparatus, office automation appliances, toys, magnetic finery, etc.

Their uses are very varied but care must be taken because they are brittle and do not flex. They are normally only safe for use below 80oC/176oF although we do stock some high and extra high operating temperature magnets. Neodymium rare earth permanent magnets are widely applied in Auto, energy-efficient voice coil Motors and Generators, Machinery, Audio/Video, and Communication Equipment, Medical devices (MRI), Office Automation, Magnetic separators, etc.

Smaller adhesive magnets are often used for jewelry clasps, magnetic therapy jewelry, magnetic earrings (one on each side of the ear), fridge magnets, model train connectors, Scalextric vehicles, re-born dolls, wargaming models, motors, science projects, etc. Larger rare earth magnets are used for science projects, actuators, separators, speakers, pumps, magnetic therapy, and circuit breakers in power stations.

Neodymium magnets are usually coated to prevent the iron from rusting. Normally this is a Nickel-Copper-Nickel plating. However, Zinc, Tin, Black Nickel, Gold, and Silver plating are also used as Epoxy resin and PTFE. The Gold and Silver plated magnets are often used to make homemade magnetic therapy jewelry. They are particularly used as a number of spheres to make necklaces or bracelets.
