Diamagnetic substances characterize by

Diamagnetic materials have no net magnetic moment without the presence of an external applied magnetic field (H). However, as an external magnetic field is applied to a diamagnetic material, the spinning electrons experience a motion, known as processing, producing electrical current and thus a magnetization (M), which is in the opposite direction to that of the external magnetic field. Therefore, diamagnetic materials have a small negative magnetic susceptibility (χ) and a permeability that is slightly lower than that of vacuum (μ₀).
