Time-varying and transient magnetic fields (0.1 Hz to 10 MHz bandwidth) from various sources – including moving subways, elevators, power sources and converters, as well as high-power RF emission sources – generate electromagnetic induction when the magnetic fields couple with conductive objects. Conductors – such as electronic equipment, scientific instruments and people – inducing currents and voltages within objects, causi interference.” In unshielded susceptible electronic equipment and signalcables, electromagnetic induction generates electromagnetic interference (EMI).
