Magnetic resonance - Wikipedia
WEBMagnetic resonance is a process by which a physical excitation is set up via magnetism. This process was used to develop magnetic resonance imaging (MRI) and nuclear magnetic resonance spectroscopy (NMRS) technology. It is also being used to develop nuclear magnetic resonance quantum computers.

WEBmagnetic resonance, absorption or emission of electromagnetic radiation by electrons or atomic nuclei in response to the application of certain magnetic fields. The principles of magnetic resonance are applied in the laboratory to analyze the atomic and nuclear properties of matter.
Resonant inductive coupling - Wikipedia
WEBResonant inductive coupling or magnetic phase synchronous coupling[4][5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
Electrical resonance - Wikipedia
WEBElectrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one. [1]
