Familiarize Electronic Components Part XIX – Inductors


Inductance is the effect caused by the magnetic field when electric current passes through a conductor. During inductance , time varying magnetic fields develop in the conductor due to changes in current flow. The unit of Inductance is Henry and the symbol used is L to honour the Physicist Heinrich Lenz. The components inducing inductance are called as Inductors which are mainly coils that are capable of concentrating magnetic field.

Fixed Inductor


Inductance (L) is the property of an electrical circuit whereby changes in current flowing in the circuit produces changes in the magnetic field such that a counter EMF is set up in that circuit or in neighboring ones. If the counter EMF is set up in the original circuit, it is called self-inductance and if it is set up in a nearby circuit then it is called mutual inductance.Fixed inductor uses multiple coils of a conducting material to store energy using a magnetic field. It belongs to the electromagnet family. The voltage produced is proportional to the rate of change in current flowing through it. The higher the number of coils and input current, the higher is the inductance
