Name a few paramagnetic substances.

When a dielectric is placed in an electric field, it gets polarized. The electric field in a polarized material is less than the applied field. When a paramagnetic substance is kept in a magnetic field, the field in the substance is more than the applied field. Explain the reason of this opposite behaviour.

Can we have magnetic hysterisis in paramagnetic or diamagnetic substances?

Depending on the magnetic property, the materials are classified into diamagnetic , paramagnetic and ferromagnetic. a. The behaviour of magnetic field lines near a magnetic substance is shown in thte figure . Which material corresponds to the figure. b. State and explain Curie's law. c. Compare paramagnetism and Ferro magnetism . Give examples of each .

Name few natural antiseptics.

Name a few brain diseases.

Why cannot we make permanent magnets from paramagnetic materials?
