Which of the following materials has permanent magnetic dipoles? Correct Answer Ferromagnetic material

Ferromagnetic Materials:
  • The ferromagnetic materials are those substances that exhibit strong magnetism in the same direction of the field when a magnetic field is applied to it.
  • when we consider some unpaired electrons, they will interact with each other between two atoms and they line up themselves in a tiny region with the direction of the magnetic field.
  • This mechanism of the ferromagnetic material is ferromagnetism.
  • It can be defined as some materials (cobalt, gadolinium, iron etc) that will become permanent magnets with the use of a magnetic field.

Properties of Ferromagnetic Materials:
  • When a rod of this material is placed in a magnetic field, it rapidly aligns itself in the track of the field.
  • It is strongly attracted by the magnet.
  • The ferromagnetism mechanism is not present in liquids and gases.
  • Some materials show permanent magnetic properties as after application of external field the moment in dipole is permanent i.e. they show permanent dipole moment.
