Differentiate the properties of soft iron and steel relating to magnetism.
The difference between the properties of soft iron and steel relating to magnetism is:
Soft iron | Steel |
1. It has high permeability. | 1. It has high permeability lower than soft iron. |
2. Magnetization is large even for a small magnetizing field. | 2. Magnetization is lower compared with soft iron. |
3. It has low retentivity. | 3. It has high retentivity. |
4. It will not retain magnetic properties. | 4. It retains magnetic properties. |
5. Useful in making temporary magnets and electromagnets. | 5. Useful in making permanent magnets. |
