Diamagnetic Material The materials that allow flow of magnetic field through them are called as Magnetic Materials. In Diamagnetic material there is no magnetism in the absence of external magnetic field. (Shown in fig. 1) When magnetic field is applied dipoles are induced and they orient in a direction opposite to external magnetic field. (As […]
