# SELF INDUCTANCE DEFINITION PDF

Noun. the production of an electromotive force in a circuit when the magnetic flux linked with the circuit changes as a result of a change in current in the same circuit. See also self-inductance, Compare mutual induction. Inductance is defined as the magnetic induction of a voltage in a current carrying wire when the current in a wire changes. In the case of self-inductance, the magnetic field created by a changing current in the circuit induces a voltage in the same wire or circuit - in other words any voltage is self-induced. Self-induction definition, the process by which an electromotive force is induced in a circuit by a varying current in that circuit. See more.

A consequence of Self inductance definition equations is that we cannot define the inductance of only a portion of a circuit, we can only define the inductance of a whole circuit, which includes how the current gets to the wire and how it returns to the source.

The self inductance definition flux incident to the whole circuit determines the inductance of the circuit and of any part of it. The magnetic flux is an indivisible entity, yet we wish to consider only a part of it, the part incident to the wire, between whatever we define to be the "ends" of the wire.

## Self-inductance - definition of self-inductance by The Free Dictionary

The total low frequency inductance internal plus external of a straight wire is: Under the effects of self inductance and changes in current induce an EMF or electro-motive force in that same wire or coil, producing what is often termed a back-EMF. As the effect is noticed in the same wire or coil that generated the magnetic self inductance definition, the effect is known as self inductance.

Self-inductance definitions There are various definitions associated with self inductance that are useful to mention. This property of the coil only opposes the changing current alternating current and does self inductance definition affect the steady current that is direct current when flows through it.

The unit of inductance is Henry H. The self-inductance of a coil is said to be one henry if a current self inductance definition of one ampere per second through a circuit produces an electro-motive force of one volt in the circuit.

Self-inductance basics When current passes along a wire, and especially when it passes self inductance definition a coil or inductor, a magnetic field is induced. This extends outwards from the wire or inductor and could couple with other circuits.

However it also couples with the circuit from which it is set up.
