Choosing A Magnet
Common Magnetic Materials
There are four classes of commercial permanent magnet materials. They are:
Ceramic
Alnico
Neodymium Iron Boron
Samarium Cobalt
Depending on the application at hand, the use of one material over another may have its benefits. The two
sample magnets provided with The Melexis Hall Effect Sensor Design Kit are both Neodymium 35 mag-
nets. They have very high flux densities for their size and should be handled with caution. These magnets
have been provided to assist in the design and construction of a Hall Effect Sensor System. The square
magnet will be referred to as magnet A, while the cylindrical magnet will be referred to as magnet B.
Graphs 1 through 4 are constructed using magnets A and B. South poles are marked with a do of red paint.
Melexis provides two types of neodymium magnets in the design kit chosen for low cost and high perfor-
mance, up to80
0
C. Neodymium is preferred for small-size magnets typically used with Hall ICs. If larger
magnet sizes or higher temperature ranges are necessary, Alnico or ceramic would be a better choice of
material.
