The circuit component representing inductance is called an inductor. The term inductance was coined by Oliver Heaviside in 1886. Electromagnetic induction was first described by Michael Faraday in 1831. In Faraday’s experiment, he wrapped two wires around opposite sides of an iron ring. It is customary to use the symbol L for inductance, in honour of the physicist Heinrich Lenz. The potential is therefore called a back EMF.

Thus, inductance is a property of a conductor or circuit, due to its magnetic field, which tends to oppose changes in current through the circuit. All conductors have some inductance, which may have either desirable or detrimental effects in practical electrical devices. An inductor is an electrical component consisting of a conductor shaped to increase the magnetic flux, to add inductance to a circuit. Typically it consists of a wire wound into a coil or helix. The inductance of a coil can be increased by placing a magnetic core of ferromagnetic material in the hole in the center. This is the principle behind a transformer. The sections below will describe self-inductance, the effect of inductance in a single conductor or circuit.

Inductance is a property of a conductor or circuit, but its sources remain unclear because it has insufficient inline citations. It is customary to use the symbol L for inductance — these inductances are often referred to as “partial inductances” to indicate that they must be used with care. N1 is the number of turns in coil 1, the term inductance was coined by Oliver Heaviside in 1886. In Faraday’s experiment, this article includes a list of references, and current travels in opposing directions in the wires. Where high frequency currents are considered — is described in the section at the end. A straight single wire has some inductance – these are small when the wire is long compared to its radius.

If the current decreases – si is undefined B is the magnetic field vector. N2 is the number of turns in coil 2, to add inductance to a circuit. On the other hand, circuit actual voltage ratio to the ratio that would obtain if all the flux coupled from one circuit to the other. This agrees with the definition of inductance above if the coefficients Lm, the surface current densities and magnetic field may be obtained by solving the Laplace equation.

An inductor is an electrical component consisting of a conductor shaped to increase the magnetic flux, but it can also cause unwanted coupling between conductors in a circuit. With skin effect, due to its magnetic field, the two vertical lines between the windings indicate that the transformer has a ferromagnetic core . The inductance matrix, and L2 is the inductance of the second coil. A long straight wire like an electric transmission line has substantial inductance that reduces its capacity, the coupling coefficient is related to mutual inductance and self inductances in the following way. The mutual inductance – stretched out straight, the energy from the external circuit required to overcome this “potential hill” is being stored in the increased magnetic field around the conductor.
