Question
Define magnetic susceptibility of a material. Name two elements, one having positive susceptibility and the other having negative susceptibility. What does negative susceptibility signify?
✓

Answer

  1. Measure of how a magnetic material responds to an external magnetic field.

Alternate Answer

Property which determines how easily the material can be magnetised.

Alternate Answer

Ratio of the magnitude of magnetisation (M) produced in the material to the intensity of magnetising field (H) or M/H.

  1. .
    1. Positive susceptibility - Para-magnetic material/Al, Ca, Cr, Li, etc.
    2. Negative susceptibility - Diamagnetic material/Bi, Cu, diamond, Au, Hg, etc.
  2. Anyone characteristics/Property of diamagnetic materials.

Alternate Answer

The material is diamagnetic in nature.

Alternate Answer

The magnetic moment, developed in the material, is opposite in direction to that of the applied external magnetic field.
