Inductance coil is performed using the principle of electromagnetic induction device operating. When a current flows through a wire, it will have a certain electromagnetic field around these wires, and this in turn will lead the electromagnetic field within the electromagnetic field in a wire range of occurrence of induction. Role wires generate an electromagnetic field to itself occurs, is called "self-inductance", i.e., a change in current generated in the wire to produce their own magnetic field changes, the influence of the magnetic field further current in the wire; effect on the electromagnetic field in the range of other guidewires generated called "mutual."
The electrical characteristics of the inductor and capacitor contrary, "blocking high frequency, low frequency pass." High frequency signal through the inductor coil will encounter strong resistance, difficult to pass; and the low frequency signal when it presented the resistance is relatively small, low-frequency signals that can be more easily through it. Inductor DC resistance to almost zero.
Resistors, capacitors and inductors, the circuit for the electrical signal they will exhibit a certain flow resistance, this resistance which we call "impedance" inductor current signal impedance presented utilizing the self-inductance of the coil. Inductor Sometimes we call it the "inductor" or "coil", with the letter "L" represents. When the wound coil, the number of turns of the coil wound we generally call it the coil "turns."
