Fundamentals of magnetic field
... The flux change occurs either because the magnetic field is changing with time (transformer inductance) or because the wire loop is moving relative to a magnetic field (motional inductance). The Faraday's induction law describes both phenomena. a) If a wire loop is fixed and the flux is varying with ...

High voltage
The term high voltage usually means electrical energy at voltages high enough to inflict harm on living organisms. Equipment and conductors that carry high voltage warrant particular safety requirements and procedures. In certain industries, high voltage means voltage above a particular threshold (see below). High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to demonstrate arcing, for ignition, in photomultiplier tubes, and in high power amplifier vacuum tubes and other industrial and scientific applications.
