Answer:

Magnetization is the process of making a magnet from a magnetic material.

Explanation:

There are many methods of magnetising a magnetic substance

- One way involves clamping the component between two electrical contacts in a special piece of equipment. Current is passed through the component and a circular magnetic field is established in and around the component. When the magnetizing current is stopped, a residual magnetic field will remain within the component. The strength of the induced magnetic field is proportional to the amount of current passed through the component.

:-A second technique involves using clamps or prods, which are attached or placed in contact with the component. Electrical current flows through the component from contact to contact. The current sets up a circular magnetic field around the path of the current.

:-Another way of indirectly inducting a magnetic field in a material is by using the magnetic field of a current carrying conductor. A circular magnetic field can be established in cylindrical components by using a central conductor. Typically, one or more cylindrical components are hung from a solid copper bar running through the inside diameter. Current is passed through the copper bar and the resulting circular magnetic field establishes a magnetic field within the test components.

Methods of magnetizing a magnetic substance

In this process a magnet made from magnetic materials. Common methods are:

Induction method: In this method, a material to be magnetized a pin is attached to the magnet, the pin(s) therefore on acquiring its magnetism acquires the magnetic poles

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

The magnetic dipole moment acquired per unit volume is known as magnetization.
