Question

Distinguish between diamagnetic paramagnetic and ferromagnetic substances

Answer 1

Explanation:

Paramagnetism refers to materials like aluminum or platinum which become magnetized in a magnetic field but their magnetism disappears when the field is removed. Ferromagnetism refers to materials (such as iron and nickel) that can retain their magnetic properties when the magnetic field is removed.

Answer 2

The key difference between diamagnetic, paramagnetic and ferromagnetic materials is that diamagnetic materials are not attracted to an external magnetic field, and paramagnetic materials are attracted to an external magnetic field whereas ferromagnetic materials are strongly attracted to an external magnetic field.
