पर्याय

• 1

• - 1

• > 1

• < 1

Answer 1

Susceptibility of ferromagnetic substance is > 1.

Explanation:

Ferromagnetic substances (like iron, nickel) get very strongly magnetised in an external field, so their susceptibility (χχ) is large and positive, much greater than 1 (can reach thousands), unlike paramagnetic (χχ small positive) or diamagnetic (χχ negative) materials.
