Skin Depth Effect of Metal Calculator

Posted by Dinesh on

The skin depth is a defined depth used to approximate the effective cross sectional area of a conductor when the skin effect is limiting that area. The resistance of a metal segment will increase as frequency rises due to the skin depth effect.

The below table listed the conductor material's permeability values.

Conductor MaterialPermeability Value (?0)
Aluminium1.00002
Copper0.999991
Gold1.0
Nickel600
Silver0.99998

Formula:

δ=ρπμf

where,
? is the skin depth
? is the frequency
? is the absolute magnetic permeability (?) = ?o x ?r
m is the permeability of free space 4*?*107 H/m
