Detailed explanation-1: -Speaker produces sound by the interaction of a permanent magnet and electromagnet. Neodymium magnet is commonly used permanent magnet in speakers because of high magnetization and demagnetization, and small-size.

Detailed explanation-2: -To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. These vibrations are the sound we hear. Speakers often contain large magnets inside of them, as a larger opposing magnetic field creates more vibrations.

Detailed explanation-3: -loudspeaker, also called speaker, in sound reproduction, device for converting electrical energy into acoustical signal energy that is radiated into a room or open air.

Detailed explanation-4: -Electromagnets are used to lift heavy masses of magnetic material and to attract movable magnetic parts of electric devices, such as solenoids, relays, and clutches.
