How do para- and dia- magnetics differ in terms of magnetization?

In summary, magnetization in a magnetic material is caused by the alignment of magnetic dipoles within the material when exposed to a magnetic field. The strength of magnetization is measured using the unit of magnetic moment, and only materials with magnetic properties can be magnetized. Factors such as the strength of the applied magnetic field, temperature, and composition of the material can affect its magnetization. Magnetization has various practical applications in everyday life, including in electric motors, medical imaging, and household items.

Welcome to the PF.

Are you asking how magnets work?

http://en.wikipedia.org/wiki/Magnet

.

I now how magnets work. This question about para- and dia- magnetics. AFAIK [tex]\vec J = \chi \vec H[/tex] and J doesn't depend from magnetic's form. But I have this question in my examination task and I don't think the answer so simple.
 

What causes magnetization in a magnetic material?

Magnetization in a magnetic material is caused by the alignment of the individual magnetic dipoles within the material. These dipoles are tiny, atomic-scale magnets that align in a specific direction when exposed to a magnetic field.

How is the strength of magnetization measured?

The strength of magnetization is measured using a unit called magnetic moment, which is typically represented by the symbol "M." This unit is measured in amperes per meter (A/m) or in the older unit of cgs (centimeter-gram-second) system, gauss (G). The higher the magnetic moment, the stronger the magnetization.

Can a non-magnetic material be magnetized?

No, a non-magnetic material cannot be magnetized because it lacks magnetic dipoles that can align in a specific direction. Only materials with magnetic properties, such as iron, nickel, and cobalt, can be magnetized.

What factors affect the magnetization of a material?

Several factors can affect the magnetization of a material, including the strength of the applied magnetic field, the temperature of the material, and the composition and structure of the material. Additionally, the presence of impurities or defects in the material can also affect its magnetization.

How is magnetization used in everyday life?

Magnetization has many practical applications in everyday life, such as in the production of electric motors, generators, and speakers. It is also used in medical imaging, data storage, and navigation systems. In addition, magnetized materials are commonly used in household items like refrigerator magnets and magnetic toys.
