Webb23 jan. 2015 · Inductance calculation of a ferrite toroid coil. We can find the formula for the inductance of a rectangular cross-section toroidal coil step by step based on fundamental laws of electromagnetism. In accordance with the Ampere's Law, we can calculate the magnetic flux density in the core at an arbitrary distance r from its central axis. [1] The ... Webb11 jan. 2024 · Self resonant coils made from the coaxial feed line allow the RF energy to be directly delivered to the antenna feed point while the self resonant coil defines the end of the radiating element and performs a function very similar to a feed line choke to keep RF energy off of the feedline back to the transmitter. This type of trap is very robust.
