NdFeB Magnets

NdFeB disc magnets are round coin-shaped Neodymium magnets of varying diameter and thickness. Generally the NdFeB disc magnets are axially magnetised i.e. one circular flat face is a North pole, the other circular flat face is a South pole with the distance between the flat faces (the disc thickness) being the distance between the poles (the magnet is magnetised along the central axis of the Neodymium disc magnet). All our NdFeB disc magnets are supplied as axially magnetised NdFeB magnets unless otherwise stated.

Detailed Description:
Feature:

sintered NdFeB 

Best power to weight ratio of all magnets. High resistance to demagnetization. Often the most cost-effective choice.


Application: 
Disc magnets are thin flat circular magnets where the thickness does not exceed the diameter. They are the most commonly used magnet shape and the most versatile. They are used in holding applications where a hole is drilled and the magnet is recessed into the hole. They are commonly used with cup assemblies to increase their holding strength.
