eng.skin-effect-frequency Calculator
Calculates the skin depth (penetration depth) for alternating current in a conductor from frequency and material conductivity. Skin depth decreases with the square root of frequency — at 60 Hz in copper, skin depth is 8.5 mm; at 1 MHz, only 0.07 mm.
Inputs
Frequency Hz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Resistivity Ohm M
Reference formula or conversion factor shown for context.
Relative Permeability
Reference formula or conversion factor shown for context.
Results
skin depth δ (mm)
The computed depth.
skin depth (µm)
The computed depth.
δ = √(ρ/πfμ)
Reference formula or conversion factor shown for context.
