प्रश्न
The susceptibility of a magnetic material is 0·9853. Identify the type of magnetic material. Draw the modification of the field pattern on keeping a piece of this material in a uniform magnetic field.
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.
