The correct option is A −0.0004
The material gets repelled by the magnetic filed, this means that it gets oppositely magnetized to that of the external field.
⇒→I and →H have opposite signs.
As, →I=χ →H,
∴ Magnetic susceptibility (χ) is negative for the material.
Also, |I|<<|H|
⇒∣∣∣IH∣∣∣<<1
∴|χ|<<1
So, χ is negative and |χ|<<1.
Hence, option (A) is correct.
