The range of magnetic susceptibility of diamagnetic materials is:

The range of magnetic susceptibility of diamagnetic materials is: Correct Answer -1 < χ < 0

CONCEPT:

  • Magnetic susceptibility: The measurement of how much a magnetic material will be magnetized in a given magnetic field is called as magnetic susceptibility.
    • It is denoted by χ.
  • Magnetic susceptibility is the ratio of magnetization and the applied magnetizing field intensity.

Magnetic Susceptibility (χ) = Magnetization/magnetizing field intensity

Diamagnetic Substance Paramagnetic substances Ferromagnetic substances
Diamagnetic substances are those which develop feeble magnetization in the opposite direction of the magnetizing field. Paramagnetic substances are those which develop feeble magnetization in the direction of the magnetizing field. Ferromagnetic substances are those which develop strong magnetization in the direction of the magnetizing field.
Such substances are feebly repelled by magnets and tend to move from stronger to weaker parts of a magnetic field. Such substances are feebly attracted by magnets and tend to move from weaker to stronger parts of a magnetic field. They are strongly attracted by a magnet and tend to move from weaker to the stronger part of a magnetic field.
Magnetic susceptibility is small and negative i.e. -1 ≤  χ ≤ 0. Magnetic susceptibility is small and positive i.e.  χ > 0 Magnetic susceptibility is very large and positive i.e. χ > 1000
Examples: Bismuth, copper, lead, zinc, etc. Example: Manganese, aluminum, chromium, platinum, etc. Example: Iron, cobalt, nickel, gadolinium, and alloys like alnico

EXPLANATION:

The range of magnetic susceptibility of diamagnetic materials is -1 ≤  χ ≤ 0.
