Key Concepts

Paramagnetism

This is a form of magnetism whereby certain materials are weakly attracted by an externally applied magnetic field. In paramagnetic materials, magnetic moments of the atoms or ions are randomly oriented in the absence of an external field but tend to align in the same direction when a magnetic field is applied, resulting in a magnetization that is proportional to the applied field.

Linear M-H Relationship

For paramagnetic substances, the magnetization (M) typically increases linearly with the applied magnetic field (H), especially at lower field strengths. This linear behavior arises because the induced alignment of magnetic moments is directly proportional to the strength of the applied field before saturation effects become significant.

Magnetic Susceptibility

Magnetic susceptibility is a measure of how much a material will become magnetized in an applied magnetic field, represented by the ratio M/H for paramagnetic materials. In paramagnetism, the susceptibility is positive and constant (or only weakly varying) under a given temperature, thus reinforcing the linear relationship between M and H observed in the magnetization curve.
