The inductance is $$L = \frac{\lambda}{I} = \frac{N\Phi}{I} $$ where \$\lambda\$ is the flux linkage - the magnetic flux links N turns.

This article describes the inductance formula and how to calculate inductance. When electric current flows through the inductor, a magnetic field is produced around it. The strength of the magnetic field depends on the inductance, current, and number of turns in a coil.
2 lut 2023 · Inductance Formula. The inductance (L) is calculated from the ratio of the induced emf (ε) and the magnitude of the rate of current change (ΔI/Δt). L = ϵ | ΔI Δt | L = ϵ | Δ I Δ t |. To measure the inductance, we use a device called an inductor in the electrical circuit.
Physically, the inductance L is a measure of an inductor’s “resistance” to the change of current; the larger the value of L, the lower the rate of change of current. Example 11.2 Self-Inductance of a Solenoid Compute the self-inductance of a solenoid withN turns, length l, and radius R with a
6 sie 2022 · N is the Number of turns. A is the Inner Core Area (πr 2) in m 2. ℓ is the length of the Coil in metres. As the inductance of a coil is due to the magnetic flux around it, the stronger the magnetic flux for a given value of current the greater will be the inductance.
When current is turned on in a solenoid, a magnetic field is generated that tries to stop the solenoid from being turned on. This property is called inductance.
Faraday’s law of induction may be stated as follows: The induced emf ε in a coil is proportional to the negative of the rate of change of magnetic flux: B d dt ε Φ =− (10.1.3) For a coil that consists of N loops, the total induced emf would be N times as large: B d N dt ε Φ =− (10.1.4) 10-3
