For inductors whose magnetic properties rather than electrical
properties matter, see electromagnet.
An inductor, also called a coil, choke or reactor, is a passive
two-terminal electrical component that stores energy in amagnetic
field when electric current flows through it. An inductor typically
consists of an insulated wire wound into a coil around a core.
When the current flowing through an inductor changes, the
time-varying magnetic field induces an electromotive force (e.m.f.) (voltage) in the conductor, described by Faraday's law of
induction. According to Lenz's law, the induced voltage has a
polarity (direction) which opposes the change in current that
created it. As a result, inductors oppose any changes in current
An inductor is characterized by its inductance, which is the ratio
of the voltage to the rate of change of current. In
theInternational System of Units (SI), the unit of inductance is
the henry (H) named for 19th century American scientist Joseph
Henry. In the measurement of magnetic circuits, it is equivalent to
weber/ampere. Inductors have values that typically range from 1 µH
(10−6 H) to 20 H. Many inductors have a magnetic core made of iron or
ferrite inside the coil, which serves to increase the magnetic
field and thus the inductance. Along with capacitors and resistors,
inductors are one of the three passive linear circuit elements that
make up electronic circuits. Inductors are widely used in
alternating current (AC) electronic equipment, particularly in
radio equipment. They are used to block AC while allowing DC to
pass; inductors designed for this purpose are called chokes. They
are also used in electronic filters to separate signals of
different frequencies, and in combination with capacitors to make
tuned circuits, used to tune radio and TV receivers.
