noun
- the property of certain materials, such as iron, to become strongly magnetized and to attract or repel other magnetic materials
Usage: physics; material science
Examples
- Iron exhibits ferromagnetism, which is why it is used in electromagnets.
- The ferromagnetism of nickel makes it useful in alloys and permanent magnets.
- Scientists study ferromagnetism to develop stronger and more efficient magnetic materials.
- Ferromagnetism occurs when the magnetic moments of atoms align in the same direction.
- Unlike paramagnetic materials, ferromagnetism persists even after the external magnetic field is removed.
