Question
If the magnetizing field on a ferromagnetic material is increased,its permeability(i) decreases(ii) increases(iii) remains unchanged(iv) first decreases and then increases
Solution
The correct answer is (ii) increases.
Here's why:
Permeability is the measure of a material's ability to conduct a magnetic field. In ferromagnetic materials, the permeability increases with the increase in the magnetizing field. This is because the magnetic domains within the material align themselves in the direction of the magnetic field, thus allowing the magnetic field to pass through the material more easily. Therefore, as the magnetizing field on a ferromagnetic material is increased, its permeability also increases.
