Inductance The property electrical circuit that opposes changes in
current. Inductive reactance directly proportional to
frequency (f) and inductance (l).
Inductive Proximity Switch type sensing switch that uses electromagnetic coil
to detect the presence metal object without coming into
physical contact with it.The symbol for inductive
reactance “XL

” The unit for impedance the ohm. An
inductor often made from coil wire and sometimes
called coil choke.17
