Permanent Magnets - Other

There are several types of permanent magnets such as Neodymium, Alnico, Ferrite (ceramic magnets) and Samarium-Cobalt. The term permanent magnet simply means that they are able to maintain a magnetic field indefinitely. Unless the they are demagnetised through the use of electric current or high temperatures they will typically retain their magnetic strength forever.

Neodymium they have properties that make them highly suitable for specialised applications where magnetic strength is not the most important requirement. Neodymium magnets are also commonly referred to as Rare Earth magnets and they are the strongest permanent magnets on the market.

Ferrite magnets, otherwise known as ceramic magnets, have a wide field and are relatively lightweight and they are highly resistant to corrosion which can be extremely helpful in outdoor environments or where exposure to corrosive elements is anticipated. Ferrite magnets are also the most affordable of the magnetic materials however they are weaker than Neodymium magnets.

Samarium Cobalt magnets are resistant to oxidation and temperature fluctuations and this type of magnetic material is used in applications where high temperatures (over 80℃), humidity or marine environments are present.

Alnico magnets are created from an aluminium, nickel and cobalt alloy and are often valued for their conductive properties. Unlike other magnetic materials, Alnico magnets are also able to operate at extremely high temperatures (450
