Magnetic force required to demagnetize the material: - Vidyadip

Question

Magnetic force required to demagnetize the material:

✓

Answer

Coercivity

Explanation:
For a ferromagnetic substance, coercivity is the intensity of the magnetic field that need to be applied to reduce the magnetization to zero when the sample's magnetization reaches saturation.
It is 'Intensity of the magnetic field' rather than 'Magnetic force'.

The binding energy of a H-atom, considering an electron moving around a fixed nuclei (proton), is $\text{B}=-\frac{\text{me}^4}{8\text{n}^2\epsilon_0^2\text{h}^2}$. (m = electron mass).
If one decides to work in a frame of reference where the electron is at rest, the proton would be moving arround it. By similar arguments, the binding energy would be,
$\text{B}=-\frac{\text{me}^4}{8\text{n}^2\epsilon_0^2\text{h}^2}$ (M = proton mass)
