Knowing the basic terminology for describing magnetic effects and properties are essential since magnetic materials can be used in inductive sensors as in the form of core. The various types of magnetic behaviour and properties of hard and soft magnetic materials (used in inductive sensor) need to be identified in order to decide on the appropriate applications in biomedical and industrial fiel

Generally magnetic forces are generated by moving charged particles thusproducing magnetic fields. The atomic movement in the material will respond to anexternal magnetic field. The external magnetic field is denoted by H, the magneticinduction in the material is denoted by B (tesla) and the magnetization by M.B = ~o(H + M) (11.1)Where 110 is the permeability of free space and M is the magnetic moment m per unitvolume of the material. The value of M depends on the type of material. Moreover everymaterial responds differently to the force of a magnetic field. There are three mainclassifications of magnetic materials. A magnet will strongly attract ferromagneticmaterials, weakly attract paramagnetic materials and weakly repel diamagnetic materials.11.2 CLASSIFICATION OF MAGNETIC MATERIALA magnetic material falls undcr five different categories: diamagnetic, paramagnetic,ferromagnetic, anti-ferromagnetic, and ferri-magnetic, as shown in Figure 11.1 and Figure11.2. Diamagnetic materials are those in which individual atoms or ions do not have netatomic or molecular movement, thus when diamagnetic material is placed in an externalmagnetizing field, it gets weakly magnetized in a direction opposite to the magnetizingfield. Antimony, bismuth, copper, diamond, gold, mercury, silver, sulphur, tin and zinc areexamples of diamagnetic material.65
