In a speaker, the magnet generates a stable magnetic field that interacts with an electric current in the coil. This interaction causes the coil to move, driving the speaker cone and producing sound waves.
In a speaker, the magnet plays a crucial role by creating a stationary magnetic field. This field interacts with the electric current passing through a coil attached to the speaker cone. As the electric current fluctuates, it generates a varying magnetic field in the coil, which causes it to move back and forth. This movement drives the speaker cone, producing vibrations that create pressure waves in the air. These pressure waves are what we hear as sound. The precise interaction between the magnet and the coil is essential for converting electrical signals into audible sound.
