A choke coil is an electronic component use to prevent high-frequency currents
that exceed the predetermined frequency.
The cooper losses of the coil produced within the choke coil not only decrease
the efficiency, but also generate heat.
In addition to the skin effect and proximity effect, an imbalanced current
caused by flux leakage around the gap increases the copper losses.
This example presents the use of a magnetic field analysis to obtain the
current distribution and copper losses of a choke coil.
