Properties of diamagnetic materials

Diamagnetic materials have following properties:

  • In a diamagnetic material, the magnetic lines of forces due to an applied field are repelled.

  • when suspended in a uniform magnetic field, diamagnetic materials set their longest axis at right angles to the direction of the field and the shortest axis is along the direction of the field.
  • when placed in a non-uniform magnetic field, the diamagnetic materials move from stronger parts of the field to the weaker parts.
  • relative magnetic permeability of diamagnetic materials is always less than unity that is

μr < 1

Reason is given in another article

  • Magnetic susceptibility if diamagnetic materials is always negative.

Reason is given in another article

  • Magnetic susceptibility of diamagnetic materials does not change with temperature, that is they do not obey Curie law

One Response to Properties of diamagnetic materials

  1. Does your book, “Electrical Engineering Materials” include the equations needed to determine the separation forces between diamagnetic materials and magnets?
