Air Core Coil Calc

The calculator determines the inductance of a single layer coil.

Air core coil calc.

Coil inductance calculator to calculate the inductance of a single layer air core coil. Air core inductor coil inductance calculator. Enter the coil diameter form diameter wire diameter see diagram. Calculate the inductance of a single layer coil of a 10 turn air core coil wound on a cylindrical former with a diameter of 2 cm.

Air core inductor designer calculator. D is the coil diameter in meters. The length of the coil is 1 cm. L d 2 n 2 18d 40l where.

Enter the coil length distance from first to last winding see diagram. Diameter and length of inductor are entered in millimetres along with the number of turns. Advantages of an air core coil. Enter the number of turns windings.

This calculator is useful when making antenna matching units low pass filters crystal sets antenna traps resonant circuits or anywhere where an air cored single layer inductor is required. L is the coil length in meters 0 8radius n is the number of turns. The calculation is based on the classic wheeler s formula for single layer inductance air core tightly wound which dates back to the radio days of the 1920s. Could this be possible.

L is the inductance in henry s. An air core inductor is an inductor that does not depend upon a ferromagnetic material to achieve its specified inductance. The following is a design tool which calculates the inductance of an air core inductor. L 0 001n2d 228d 2 254l where.

The inductor is a common school use transformer 5000 turn coil with wire diameter about 0 15mm the official air core value is 0 6h however when i calculate the iron core got a result of 105h. D coil diameter in inches inches l coil length in inches inches n number of turns inductance. Get help for the inductor designer close. Some inductors are wound without a bobbin and just air as the core.
