Neodymium magnets are a member of the Rare Earth magnet family and are the most
powerful permanent magnets in the world. They are also referred to as NdFeB
magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe)
and Boron (B). They are a relatively new invention, first manufactured in 1984
and have only recently become affordable for everyday use.
Neodymium
'Rare Earth' Magnets have a high resistance to demagnetization, unlike
most other types of magnets. They will not lose their magnetization around other
magnets or if dropped. They will however, begin to lose strength if they are
heated above their maximum operating temperature, which is 176°F (80°C)
If you've never handled neodymium magnets before, you will be amazed at their
strength. Neodymium magnets are over 10 x stronger than the strongest ceramic
magnets. If you are currently using ceramic magnets in your project, you could
probably use a much smaller neodymium magnet and have greater force.
Neodymium magnets also have some limitations due to their corrosion behaviour. In
humid applications, a protective coating is highly recommended. Coatings which
have been used successfully include E-coat (a liquid dip epoxy coating), dry
electrostatic spray epoxy, nickel plating and combinations of these coatings.
Changes in composition and processing over the past several years have resulted
in significant improvements in corrosion resistance and high temperature
performance.
Just like ferrite magnets neodymium magnets come in the same wide array of
shapes and sizes, but because of their greatly increased size it is possible to
use a measurably smaller neodymium magnet and still have an equal or greater
strength than that of a ferrite magnet. This is one of the main reasons why
neodymium magnets are much more widely used for healing purposes than ferrite,
as a much smaller and lighter weighing magnet can be used.
• They are the strongest magnets available approx 10 times stronger than ferrite
magnets.
• They are very lightweight.
• They do not demagnetise very easily and can with stand temperatures up to 80
C.
• They can be manufactured to a very small size e.g.2mm x 2mm and still have a
strength of several thousand gauss.
The main drawback of neodymium magnets is that they have a low resistance to
corrosion. To prevent corrosion from water, they must be coated with plating or
an epoxy resin.
Neodymium magnets are used for all healing applications. They are the first
choice due to their strength and size. They will also stay magnetised for at
least 10 years, so they are a very economical choice for users. Most magnetic
jewellery, straps, wraps and bedding will contain neodymium magnets.
