• In electromagnetism and electronics, inductance is the ability of an inductor to store energy in a magnetic field. • To add inductance to a circuit, electronic components called inductors are used, typically consisting of coils of wire to concentrate the magnetic field and to collect the induced voltage.
Inductance

•The unit : henry (H), which is defined as the production of one volt of counter-emf in a coil when current has a change of one ampere per second. • The symbol : L • Inductance can be increased by looping the conductor into a coil which creates a larger magnetic field.

a) Air core inductors Inductance value is micro henry or less and usually used in
high frequency. For example, this inductor used as radio
frequency choke to prevent the current radio frequency
(high frequency) of a particular route in the circuit.
b) Iron core-coils The iron core is laminated iron core coated with a thin
insulator. Inductance value of the iron core is a few
millimeter to several henry. It is used as a low-frequency
filter in the voltage supply circuit. It is also used as a choke in the circuit of “lampu pendaflour”

(c)Powder iron core inductors and ferrite core inductors
Powder iron core is produced with the appearance of
iron powder covered by insulation. Ferrite core is made
of non-conductive magnetic material. By using powder
iron core or ferrite iron core, the inductance will be
higher and the size can be reduced.
They have three forms, namely a solenoid, toroid and
pot core. Solenoid type 1micro henry inductance value
or less while the pot core and toroid have the
inductance values between a few to a few milli
microhenry.
Normally used in radio tuning circuits.

VARIABLE INDUCTOR
- A coil whose effective inductance can be changed. - can be constructed by making one of the terminals of the device a sliding spring contact that can move along the surface of the coil, increasing or decreasing the number of turns of the coil included in the circuit. -An alternative construction method is to use a moveable magnetic core, which can be slid in or out of the coil. - Moving the core farther into the coil increases the permeability, increasing the inductance.

- Many inductors used in radio applications (usually less than100 MHz) use adjustable cores in order to tune such inductors to their desired value, since manufacturing processes have certain tolerances (inaccuracy). - Sometimes such cores for frequencies above 100 MHz are made from highly conductive non- magnetic material such as aluminum. - They decrease the inductance because the magnetic field must bypass them.

Basic Construction -It is basically constructed using a copper wire wrapped around a core make of ferromagnetic material or just around the air. - Using ferromagnetic material help to confine the magnetic flux within the coil and hence increasing the inductance of the coil. -The copper wire must have good insulation to prevent shorting of the wires to one another. - In some circuitry, there is a need to change or tune the value of the inductance hence an adjustable core type is used. - An inductor is usually constructed as a coil of conducting material, typically copper wire, wrapped around a core either of air or of ferrous material. - Core materials with a higher permeability than air confine the magnetic field closely to the inductor, thereby increasing the inductance.
A typical toroidal coil that is wrapped around an iron core
