Air Core Coil – not a magnetic core

When a inductor does not use a magnetic core, air core coil have low inductance nut used at high frequencies and they are free from energy losses. This electrical energy calculator is a great tool to calculate air core coil inductance.

Air Core Coil

To calculate Air Core Coil:

  • Coil Diameter (d)


  • Coil Length(l)


  • Number of turns (n)


  • Inductance
