Question

what is meant by penetrating ability of the magnetic field

Answer 1

hay mate your ans......
Penetration depth is a measure of how deep light or anyelectromagnetic radiation canpenetrate into a material. ... Whenelectromagnetic radiation is incident on the surface of a material, it may be (partly) reflected from that surface and there will be a field containing energy transmitted into the material.
hope its helps you dear...

Answer 2

The penetrating ability of the magnetic field is meant as penetration depth.

Explanation:

• The measurement of the depth a electromagnetic wave penetrates through the material is called penetration depth.
• The intensity of the waves reduces to 1/e of the original intensity.
• The penetration depth of the electromagnetic wave depends on the nature of the atom in the material.
• The penetration depth is a function of wavelength in a given material.
• The intensity of electromagnetic wave is given as:

I(z) = I₀$e^{-\alpha z}$
