A self resonant coil refers to a coil in a circuit that is not a pure inductance, but becomes capacitive (and hence self-resonant) at higher frequencies due to inter-turn capacitance. An example might be an RF coil designed for use at 100 MHz (FM band) that will self-resonate at 200 MHz due to inter-turn capacitance.

A self-resonant system refers to a system or component that has a natural resonant frequency at which it vibrates or oscillates without any external force. In other words, it is a system that can sustain oscillations at a specific frequency without the need for a constant external energy input.

For example, a self-resonant coil is a type of electronic component that has a natural resonant frequency at which it can generate and sustain an electromagnetic field. This frequency is determined by the physical properties of the coil, such as its size, shape, and material. When an alternating current is passed through the coil, it will vibrate or oscillate at its self-resonant frequency, producing a strong and stable electromagnetic field.

Self-resonant systems are important in various fields, such as electronics, acoustics, and mechanics. They are commonly used in electronic circuits, antennas, and musical instruments. Understanding and controlling the self-resonant frequency of a system is crucial in designing and optimizing its performance.
