Calculate the self inductance of a straight wire considering skin effect

Wire Self Inductance Formula

Formula: L = 0.002 × l × (ln(2l/d) - 1 + d/4δ)

Where:

  • L = Self inductance (H)
  • l = Wire length (m)
  • d = Wire diameter (m)
  • δ = Skin depth
  • ln = Natural logarithm

Note: Skin depth (δ) is calculated using frequency and material properties

About Wire Self Inductance Calculator

Physical Principles

Wire geometry affects inductance values. Length determines magnetic field distribution. Diameter influences flux density. Current flow creates magnetic fields. Frequency impacts skin effect depth. Material properties alter magnetic behavior.

Frequency Response

Skin effect modifies current paths. Higher frequencies concentrate current flow. Surface current density increases. Effective resistance changes. Inductance varies with frequency. Phase shifts occur naturally.

Design Factors

Wire spacing affects coupling. Bend radius changes inductance. Temperature impacts resistance. Shielding modifies fields. Proximity effects emerge. Material selection matters.

Practical Limits

Maximum current defines size. Heat dissipation requires space. Magnetic saturation sets bounds. Frequency range limits operation. Physical constraints affect layout. Environmental factors influence performance.

Circuit Integration

Component placement affects coupling. Lead length adds inductance. Ground paths matter. Shield connections reduce interference. Layout techniques minimize noise. System integration requires planning.
