The respective type of magnetisation depends on the desired application, shape and material of the magnets used. So, for example, when using different magnetisation types with otherwise identical shapes, differences in the relationship between adhesive force and air gap are achieved.
Also, the raw magnet used plays a significant role. If it is made of an anisotropic material, the first four magnetisation types mentioned below may generally be used. If the magnet is made of an isotropic material, then, as a rule, the last two types of magnets listed below may be used.
