Question

state two properties of ferro magnetic substance... plz two gud points​

Answer 1

Answer:

In ferromagnetic materials, the magnetic lines of forces due to the applied magnetic field are strongly attracted towards the material.

All ferromagnetic materials become paramagnetic above a temperature called Curie temperature.

Answer 2

Answer:

Ferromagnetic substances are those in which each atom or molecule has a strong spontaneous net magnetic moment. These substances exhibit strong paramagnetic properties.

1. The susceptibility and relative permeability are very large. (For example : ?r for iron = 200,000)

2. Susceptibility is inversely proportional to the absolute temperature.
