Measuring Magnetization by Force:

By taking different types of magnetic materials in the solid form, we can relatively measure the change in the force resulting from its magnetization.

Consider the magnetic materials having negative and positive susceptibility. As shown in Figure 28.02, taking the materials having negative susceptibility give a repulsive force away from increasing field, pushing the sample up, while the materials having positive susceptibility give an attractive force, drawing the material towards the field maximum.
