उत्तर
As we know that susceptibility of a paramagnetic substance is positive but small. Hence, the given magnetic material is paramagnetic in nature.
When a specimen of a paramagnetic substance is placed in a magnetising field, the magnetic field lines prefer to pass through the specimen rather than through air. Thus, magnetic induction B inside the sample is more than the magnetic induction B0 outside the sample.
