All About About Rare Earth Magnets

Rare earth magnets are powerful magnets that contain a number of materials such as cobalt, nickel, and iron. In most cases, the units are derived from alnico, ceramic, samarium cobalt and neodymium.

Their strongest magnets are made of neodymium. The good side with these units is that they easily fit in a 10-pound steel block.

The magnetic forces in the unit are determined by finding out the ability of certain alloys that will be a magnet.

You can buy large neodymium magnets at


One of the features used in determining the magnetic strength is Gauss per cubic inch which usually measures the intensity of magnetic flux. There are also oersteds which are a measurement of the coercivity of the magnet.

The strength of a magnet is determined by multiplying the Gauss per cubic inch and oersteds. When you multiply the two you get MGOe (oesterids megagauss).

Rare earth unit applied in a number of areas. Some of the most common applications are computer hard drives, audio speakers, fishing reel brakes, high-performance AC servo motors, wind turbine generators, traction motors, mechanical-powered flashlight, and a permanent magnet motor.

They can also be used in industrial applications where they are used in maintaining the purity of the product, quality control, and protection equipment.

If you have the skills, you can easily create a unit. To get them you need iron boron, neodymium, and steel. The first thing you need to do is to grind solid ingot and neodymium iron boron into powder and powder compact into a mold.
