Question

What is magnetization? state and explain the two method of magnettization

Answer 1

Answer:

There are two methods generally used to magnetize permanent magnets: static magnetization and pulse magnetization. The first magnetizes via a static electromagnetic field and normally only generates a magnetic field of up to 2MA/m.

Answer 2

Explanation:

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 volumemagnetization in a magnetic field, which disappears when the magnetic field is removed. Ferromagnetic and ferrimagnetic materials have strong magnetization in a magnetic field, and can be magnetized to have magnetization in the absence of an external field, becoming a permanent magnet. Magnetization is not necessarily uniform within a material, but may vary between different points. Magnetization also describes how a material responds to an applied magnetic field as well as the way the material changes the magnetic field, and can be used to calculate the forces that result from those interactions. It can be compared to electric polarization, which is the measure of the corresponding response of a material to an electric field in electrostatics. Physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume.[1] It is represented by a pseudovector M.
