Symbols - Inductor

	Iron Core Inductor These are used as substitutes to ferrite core inductors. Ferrite core or Ferromagnetic inductors have high permeability and require air gap to reduce it. Iron powdered core inductors have this air gap integrated.
	Ferrite Core Inductors Core material, in this type of inductors is made of ferrite material. These are mostly used to suppress the interference of electromagnetic waves.
	Center Tapped Inductors These are used in coupling of signals
	Variable Inductors Movable ferrite magnetic core variable inductors are most common. The inductance is varied by sliding the core in or out of the coil.
