What is the force produced by a magnetic field?

What is the force produced by a magnetic field?

The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

What is the net magnetic moment of an atom of a diamagnetic material?

In diamagnetic materials the net magnetic moment of atoms is zero.

Do diamagnetic materials have permanent magnetic moment?

In general, a diamagnetic material does not have permanent magnetic dipoles; the induced magnetization tends to reduce the total magnetic field.

What is the magnetic susceptibility of diamagnetic substance?

The magnetic Susceptibility of a diamagnetic substance is negative and very slightly less than one and of the order of10−5. There is no appreciable variation of diamagnetism with temperature that is susceptible and independent of temperature.

How do you find the force of a magnetic field?

We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ to find the force.

Why is the magnetic force perpendicular to the magnetic field?

The superficial answer is simply that the Lorentz (magnetic) force is proportional to v×B, where v is the particle velocity and B is the magnetic field. Since the vector cross product is always at right angles to each of the vector factors, the force is perpendicular to v.

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.

What is net magnetic moment of an atom?

The net magnetic moment of an atom is the vector sum of its orbital and spin magnetic moments. In materials you can make bar magnets out of, however, neighboring atoms interact in such a way that their magnetic moments are aligned. In other words, the material acts like one big current loop, producing a magnetic field.

How does diamagnetic material in a magnetic field changes?

In diamagnetism, another magnetic phenomenon, electrons within a substance respond to the outside magnetic field by, essentially, spinning faster. All this spinning generates magnetic forces that resist the outside field. Because all atoms possess electrons, all materials are diamagnetic to some degree.

What are diamagnetic substances give properties of diamagnetic substances?

In simple terms, diamagnetic materials are substances that are usually repelled by a magnetic field. Electrons in an atom revolve around the nucleus thus possess orbital angular momentum. The resultant magnetic momentum in an atom of the diamagnetic material is zero.

What is magnetic force example?

Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.

What is magnetic force explain with an example?

The force exerted between a magnet and a moving, electrically charged particle. Magnetic force is defined as the power that pulls materials together. An example of magnetic force is how a magnet can pick up coins.

What is the magnetic moment of diamagnetic materials?

The diamagnetic materials do not have magnetic moment in absence of applied field. When magnetic field is applied, electron spinning produces a magnetization (M) in a direction opposite to applied field. Materials showing diamagnetic effect are a very small number. Magnetic susceptibility is small and negative.

How does a magnetic field repel diamagnetic materials?

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force.

How to differentiate between paramagnetic and diamagnetic substances?

1. Differentiate Between Paramagnetic and Diamagnetic Substances. 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. These substances have no unpaired electrons.

Do diamagnetic materials have negative magnetic susceptibility?

Therefore, diamagnetic materials have a small negative magnetic susceptibility (χ) and a permeability that is slightly lower than that of vacuum ( μ0 ). Although the diamagnetic effect occurs in all materials, it is too weak as compared with other magnetic effects in magnetic materials.
