Neodymium Disc Magnets

Also known as rare earth disc magnets, neodymium magnets are the perfect combination of small size and maximum strength. Since the diameter is larger than the thickness, the disc has a very strong magnetic field and high coercivity. This type of permanent magnet is used in different applications such as metal separation, magnetic therapy, booklet closing, school science experiments, jewelry making, packaging, bookbinding, point-of-sale displays, and appliances, to name a few.

Neodymium magnets are graded according to their strength, which is related to the magnetic flux density output per unit volume. Higher values ​​indicate stronger magnetic forces, ranging from N35 to N52. The letter after the grade indicates the maximum operating temperature, ranging from M (up to 100 degrees Celsius) to EH (200 degrees Celsius).
