Enter the electrical resistivity, angular frequency, and magnetic permeability into the calculator to determine the skin depth.

## Skin Effect Formula

The following formula is used to calculate a skin effect depth.

s = SQRT ( 2*p/w*u)

- Where s is the skin effect depth
- p is the electrical resistivity.
- w is the angular frequency (2*pi*f)
- u is the magnetic permeability

## Skin Effect Definition

A skin effect is the phenomena that occur in alternating currents that cause a thin outside layer of conductor to carry all of the currents. The depth of this layer is called the skin effect depth.

## Skin Effect Example

How to calculate skin effect depth?

**First, determine the resistivity.**Measure or calculate the resistivity of the system.

**Next, determine the angular frequency.**This is equal to 2*pi*f, where f is the frequency in hz.

**Next, determine the magnetic permeability.**Calculate the magnetic permeability.

**Finally, calculate the depth.**Calculate the depth of the skin effect using the formula above.

## FAQ

**What is a skin effect?**

A skin effect is a process in which the majority of the current of an alternating current travels along with a small layer of a wire due to the interaction of the electric and magnetic fields.
