A magnetic buzzer is an electronic device that produces sound by using a magnetic field to vibrate a diaphragm or a plate. The buzzer consists of a coil and a magnet, and when an electrical signal is applied to the coil, it creates a magnetic field that attracts the magnet towards it. This movement creates a vibration in the diaphragm or plate, producing sound waves.

Magnetic buzzers are commonly used in various applications, such as alarms, doorbells, electronic toys, and other devices that require audible feedback. They are often preferred over piezoelectric buzzers because they have a simpler design, consume less power, and produce a louder and more distinct sound.

Magnetic buzzers come in various shapes and sizes, and their sound output can be adjusted by changing the voltage or frequency of the electrical signal applied to the coil. They are often available as standalone components or integrated into larger electronic systems.
