| Cobalt, which is naturally ferromagnetic, provides resistance to demagnetization in several groups of permanent magnet materials. |
| To make inner layer ferromagnetic, more carburisation and hence longer period of service exposure is needed. |
| The construction of a transformer includes a ferromagnetic core around which multiple coils, or windings, of wire are wrapped. |
| In ferromagnetic materials, the atoms' magnetic moments are all aligned in the same direction. |
| Most materials are not ferromagnetic, but there are a variety of magnetic effects that other materials exhibit. |
| To achieve this, the tip of an AFM cantilever is coated with a ferromagnetic layer a few nanometers thick. |
