4mm Neodymium Disc Magnets, 10 Pack - 

NdFeB or Rare Earth 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.
