Comparison of magnetic properties of soft iron and steel.
| Property |
Soft Iron |
Steel |
| 1. Saturation magnetisation (Imax) |
more (good for strong magnets) |
less (not good for strong magnets) |
| 2. Retentivity |
more but unstable (good for electromagnets) |
less but stable (good for permanent magnets) |
| 3. Coercivity |
less (not good for durable magnets) |
more (good for durable magnets) |
| 4.Hysteresis loss |
less (good for transformer and choke cores and telephone diaphragms) |
more (not good for repeated magnetisation) |
