INDUCTOR AND INDUCTANCE
- also called a choke, another passive type electrical component design to take advantages to this relationship by producing a much stronger magnetic field than one that would be produced by a simple coil.
- symbol L
- the property of an electric circuit by which an electromotive force is
induced in it as the result of changing magnetic flux.
- unit: Henry
- temporary magnet production due to flow of electric current.
- production process electric form magnet.
TYPES OF INDUCTOR
i) air core
ii) iron core
iii) ferrite core
i) core loss
CONSTRUCTION OF CONDUCTOR
- usually constructed as a coil of conducting material, typically copper wire, wrapped around a core either of air or ferrous material
- Core materials with higher permeability than air confine the magnetic field closely to the inductor, thereby increasing the inductance
- some enclose the wire completely in ferrite and are called
- Some inductors have an adjustable core, which enables changing of the inductance.
- Small inductors can be etched directly onto a printed board by laying out the trace in a spiral pattern.
