This document discusses inductors, which are passive electronic components that store electrical energy as magnetic energy. It defines an inductor as a coil of conducting material, typically copper wire, wrapped around a core. The more turns of the coil and the stronger the magnetic field generated. Inductors are used in applications such as filters, sensors, and transformers. They work by generating a magnetic field when electricity flows through the coil.

4. Whatisinductor?
An inductor is a passive
electronic component which is
capable of storing electrical
energy in the form of magnetic
energy.

8. An inductor usually consists of a
coil of conducting material,
typically insulated copper wire,
wrapped around a core either of
plastic (to create an air-
core inductor) or of a
ferromagnetic (or ferrimagnetic)
material; the latter is called an
"iron core" inductor.
Construction

9. INDUCTANCE
Basically, it uses a conductor that is wound into a coil, and when
electricity flows into the coil from the left to the right, this will generate
a magnetic field in the clockwise direction.
The more turns with which the conductor is wound around the core, the
stronger the magnetic field that is generated. A strong magnetic field is
also generated by increasing the cross-sectional area of the inductor or
by changing the core of the inductor.

11. USES
Inductors are used in
tuning circuits.
These are used as sensors.
It is also used to store
energy in a device.
Inductors are used in
induction motors.
It is used as transformers.
Inductors are used as
filters.
