What is diamagnetism explain?

Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances, the weak diamagnetic force is overcome by the attractive force of magnetic dipoles in the material.

What is the reason for diamagnetism?

Diamagnetism is a universal property of the atom since it arises from the motion of electrons in their orbits around the nucleus. Electrons moving in this way represent electrical circuits and it follows from Lenz’s law that this motion is altered by an applied field in such a manner as to set up a repulsive force.

Which law can explain diamagnetism?

According to Lenz’s law, any current induced by a magnetic field gives rise to a magnetic field opposing the original inducing field.

What are diamagnetic substances explain the diamagnetism on the basis of electron theory?

Whenever two electrons are paired together in an orbital, or their total spin is 0 , these are called diamagnetic electrons. Diamagnetic materials are repelled by a magnetic field. An applied magnetic field in these materials creates an induced magnetic field in an opposite direction. Thus, causing a repulsive force.

What is Diamagnetism for kids?

Diamagnetism is a type of magnetism. They very weakly repel magnets. Most substances are diamagnetic. It was discovered in 1778 when someone saw that bismuth and antimony repelled a magnet. Water can be repelled by a magnet because it is diamagnetic.

What is the difference between paramagnetism and diamagnetism?

Paramagnetic materials are attracted by external magnetic fields whereas diamagnetic materials are repelled. Paramagnetic materials have at least one unpaired electron in the system, but diamagnetic materials have all their electrons paired.

Which of the following is diamagnetic?

Bismuth is one of the naturally occurring elements with negative magnetic susceptibility value. Thus, it is a diamagnetic substance. Thus, option D is the correct answer.

What is the diamagnetic substance?

A diamagnetic substance is one whose atoms have no permanent magnetic dipole moment. When an external magnetic field is applied to a diamagnetic substance such as bismuth or silver a weak magnetic dipole moment is induced in the direction opposite the applied field.

Which is an example of Diamagnetism?

Some of the most common examples of diamagnetic substances are Copper, Zinc, Bismuth, Silver, Gold, Antimony, Marble, Water, Glass, NACL, etc.

What is meant by the term paramagnetism and diamagnetism?

The term paramagnetic refers to the attraction of material to an external magnetic field. The term diamagnetic refers to the repulsion of material from an external magnetic field. These substances have at least one unpaired electron.
