Calculate the length of the coil needed for an aircore inductor.
aircoreLength(
2cm, // diameter
10uH, // inductance
20 // number of turns
)
| diameter | The diameter of the coil. |
| inductance | The inductance of the coil. |
| numberOfTurns | The number of turns of wire in the coil. |
| return value | The length of the coil. |
