Question

please freinds give me a right answer please i give you thanks and make you brainliest​

Answer 1

Explanation:

Here is the answers for above questions.

Answer 2

1. Magnetic Induction is one of the ways making magnetic materials like steel and iron into magnets. ... Induced magnetism is a temporary process. If the permanent magnet is removed, the magnetic material will usually lose its induced magnetism.

2. Susceptibility :- The susceptibility is a quantification for the change of an extensive property under variation of an intensive property.

Example :- Magnetic susceptibility.

Retentivity :- The property of the magnetic material to retain magnetism even in the absence of the magnetizing field is known as retentivity or remanence.

3. Permeability is the quality or state of being permeable—able to be penetrated or passed through, especially by a liquid or gas.

4.An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it.

Peculiarities:-

(i) An electromagnet is temporary in nature.

(ii) An electromagnet is made of a soft iron core.

(iii) The magnetic field strength can be changed.

(iv) An electromagnet can be easily demagnetized by switching off the current.
