Inductor device manufactured have specific inductance. An
inductor often made from coil wire and sometimes
called coil choke.The symbol for
impedance “Z.14
Inductance The property electrical circuit that opposes changes in
current.
Air Core Inductor

Inductive Proximity Switch type sensing switch that uses electromagnetic coil
to detect the presence metal object without coming into
physical contact with it.
” The unit for impedance the ohm. Impedance is
the vector sum resistance and reactance.
