Question

What is diamagnetic materials, paramagnetic materials, ferromagnetic materials?​

Answer 1

Diamagnetic materials have their magnetic dipoles align opposite to an applied field, becoming unmagnetized when the field is removed. Paramagnetic materials are magnetized in an external field but lose their magnetism when the field is removed. Ferromagnetic materials are composed of magnetic domains with aligned dipoles and remain magnetized after the field is removed.

Step-by-step explanation:

Diamagnetic materials are materials whose magnetic dipoles align oppositely to an applied magnetic field. When the field is removed, the material becomes unmagnetized. Examples of diamagnetic materials are copper and bismuth.

Paramagnetic materials are materials like aluminium or platinum that become magnetized in an external magnetic field, similar to ferromagnetic materials. However, they lose their magnetism when the external magnetic field is removed.

Ferromagnetic materials are materials such as iron or its alloys. They consist of tiny magnetic domains, where the magnetic dipoles align in the same direction due to strong coupling. Even when the field is turned off or reversed, ferromagnetic materials remain magnetized.

Answer 2

Diamagnetic materials are those that some people generally think of as non-magnetic, and include water, wood, most organic compounds such as petroleum and some plastics, and many metals including copper, particularly the heavy ones with many core electrons, such as mercury, gold and bismuth.

Paramagnetic Materials: These are metals that are weakly attracted to magnets. They include aluminum, gold, and copper. The atoms of these substances contain electrons most of which spin in the same direction but not all.

Ferromagnetic materials are those materials which exhibit a spontaneous net magnetization at the atomic level, even in the absence of an external magnetic field. When placed in an external magnetic field, ferromagnetic materials are strongly magnetized in the direction of the field.
