Curie temperature is the temperature above which.
1 a ferromagnetic material becomes para- magnetic
2 a paramagnetic material becomes diamagnetic
3 a ferromagnetic material becomes dia-magnetic
4 a paramagnetic material becomes ferro-magnetic
Explanation:
A When ferromagnetic materials are heated, they lose their magnetic properties and are converted into paramagnetic materials. This temperature is called curie temperature. Therefore, curie temperature is the temperature above which ferromagnetic material becomes paramagnetic material.

Which of the following statement is true for relative magnetic permeability?
1 It is dimensionless
2 It is unit less
3 Its value is greater than 1000 for iron
4 All of the above
