# Frequent question: What is the difference between magnetic field and Magnetising field?

Contents

Difference between Magnetic Intensity and Intensity of Magnetisation. The magnetic intensity defines the forces that the poles of a magnet experiences in a magnetic field whereas the intensity of magnetisation explains the change in the magnetic moment of a magnet per unit volume.

## What is the difference between magnetic field and magnetic field strength?

Simply stated, a magnetic field is analogous to electrical voltage, while magnetic flux is analogous to electrical current. Another way to put it is that magnetic field strength (H in amperes per meter) is the amount of magnetizing force. …

## What is meant by Magnetising field?

In classical electromagnetism, magnetization or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. … Physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume.

## What is magnetic field and flux?

Magnetic flux is a measurement of the total magnetic field which passes through a given area. … The angle at which the field line intersects the area is also important. A field line passing through at a glancing angle will only contribute a small component of the field to the magnetic flux.

## What is H in magnetic field?

The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization. …

## Where is the magnetic field the strongest?

The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

## How magnetic field is created?

Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.

## Why do magnetic fields exist?

Magnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature.

## Why is B used for magnetic field?

What is the historical reason for denoting magnetic filed “B”? … A is still used for vector potential, B for magnetic field (or magnetic induction or flux density, depending who you ask), H for magnetic intensity, etc. Maxwell used C and G for other vectors that I don’t recall at the moment.

## What is magnetic flux made of?

Magnetic flux is what generates the field around a magnetic material. It consists of photons, however, unlike the light we receive from the Sun, it is at a much lower frequency.

## What is difference between B and H?

B is magnetic flux density, whereas H is magnetic field intensity.

## What is the basic cause of induced emf?

Magnetic Effects of Electric Current

The basic cause of induced emf is the change of magnetic flux linked with a closed circuit.

## Which unit is Tesla?

Tesla, unit of magnetic induction or magnetic flux density in the metre–kilogram–second system (SI) of physical units. One tesla equals one weber per square metre, corresponding to 104 gauss. It is named for Nikola Tesla (q.v.).

## What is K in magnetic field?

The magnetic field is then B = k *I/r where k = constant.

## What is B and H in physics?

Answered September 2, 2018. H is known as magnetic field intensity and B is known as magnetic flux density. and H is constant, and is only affected from its origin(might be a current carrying wire or a magnetic material) , ie even if the material inside which the flux is being calculated is changed, H remains constant.
