Detailed Solution
Download Solution PDFThe correct answer is option 1.
Difference between hard and soft magnetic material:
|
Hard magnetic material |
Soft magnetic material |
|
Hard magnetic materials are those types of magnetic materials that maintain a constant magnetic property after magnetization at once. |
A type of magnetic material which can be easily magnetized and demagnetized is known as soft magnetic material. |
|
The area of the hysteresis loop for hard magnetic materials is large, consequently, these materials have large hysteresis loss. |
The area of the hysteresis loop of the soft magnetic materials is small |
|
Materials like iron, nickel, and cobalt are common examples of hard magnets. |
An electromagnet is an example of a soft magnet. |
|
Hard magnetic materials have a large value of retentivity and coercivity |
Soft magnetic materials have a small value of retentivity and coercivity. |
