Air Core Inductor

An inductor is an electrical component used to store the energy resulting from current passing through it in a magnetic field. An inductor is made by wrapping a conducting wire into a coil around a central core, with each turn of the wire termed a winding. The number of windings in the coil is directly related to the inductance. Air core inductors use either non-magnetic coils or no coil at all instead of a ferromagnetic coil. The use of an air core ensures a lower peak inductance, but also reduces the energy losses associated with ferrite inductors. The lack of core losses allows air core inductors to be operated at high frequencies.
