Theory:

  • Ferromagnetic materials can align themselves parallel to the magnetic field's direction when suspended in an external uniform magnetic field.
  • They migrate quickly from the weaker part and move towards the stronger part when suspended in a non-uniform magnetic field.
  • They are strongly magnetised in the direction of the magnetic field.
  • The external temperature affects the magnetic properties of these substances.

Important!
A ferromagnetic material, when heated, turns to a paramagnetic material. While heating, the magnetic properties of a ferromagnetic material is altered and turns into a paramagnetic material.
 
Curie temperature is the temperature at which the ferromagnetic material becomes paramagnetic material.
