A loop inductance calculator is a tool used to calculate the inductance of a loop of wire. Inductance is a property of an electrical circuit that describes the amount of energy stored in the magnetic field created by the current flowing through the circuit.

A loop of wire is a simple example of an inductor. When a current flows through the wire, a magnetic field is created around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire and the geometry of the wire.

The inductance of a loop of wire depends on several factors, including the radius of the wire, the number of turns in the loop, and the spacing between the turns. A loop inductance calculator takes these factors into account and provides an estimate of the inductance of the loop.

To use a loop inductance calculator, you typically input the radius of the wire, the number of turns in the loop, and the spacing between the turns. The calculator then uses a formula to calculate the inductance of the loop based on these parameters.

One commonly used formula for calculating the inductance of a loop is:

L = μ₀ × n² × A / l

where L is the inductance in henries, μ₀ is the permeability of free space (4π × 10⁻⁷ H/m), n is the number of turns in the loop, A is the area of the loop in square meters, and l is the length of the loop in meters.

Using a loop inductance calculator can be helpful in designing electrical circuits that require inductors. By knowing the inductance of a loop, you can select the appropriate components and ensure that your circuit will operate as intended.
