Magnethelisüsteemides refers to magnetic audio systems. These systems utilize magnetic principles to record, reproduce, or amplify sound. The most common application historically has been magnetic tape recording, where sound waves are converted into varying magnetic patterns on a tape. When this magnetized tape passes a playback head, the magnetic variations induce an electrical signal, which is then amplified to produce sound. Early forms of magnetic recording included wire recording, predating magnetic tape.

In modern audio technology, while magnetic tape is less prevalent for consumer use, magnetic principles remain fundamental in various components. Speakers, for instance, rely on electromagnets. An electrical audio signal passes through a coil of wire attached to a diaphragm. This coil is situated within a magnetic field created by a permanent magnet. The changing electrical current in the coil causes it to move back and forth, vibrating the diaphragm and producing sound waves. Similarly, magnetic pickups in electric guitars and basses work by sensing the vibrations of steel strings in a magnetic field, converting these vibrations into an electrical signal. The development of magnetic audio systems has been a significant factor in the evolution of audio recording, broadcasting, and playback technologies.
