It is commonly used in various electronic devices such as alarm systems, timers, and household appliances. The working principle of a magnetic buzzer involves the interaction between a magnetic field and a diaphragm to produce sound. In this article, we will discuss the working principle of a magnetic buzzer in detail.We are professional manufacturer of Cast iron pipe fittings,Applicable to EN877,Gray iron fitting,Drainage fittings,Drainage fittings. 1. Introduction to Magnetic Buzzer: A magnetic buzzer consists of two main components: a coil and a diaphragm. The coil is wound around a bobbin and is connected to an electrical circuit. When an electrical current passes through the coil, it generates a magnetic field. The diaphragm, on the other hand, is a thin piece of material that vibrates in response to the magnetic field. These vibrations produce sound waves, which are then amplified and emitted by the buzzer. 2. Electromagnetic Induction: The working principle of a magnetic buzzer is based on the phenomenon of electromagnetic induction. Electromagnetic induction is the process of generating an electromotive force (EMF) in a conductor when it is exposed to a changing magnetic field. This principle was first discovered by Michael Faraday in the early 19th century. In the case of a magnetic buzzer, the coil acts as the conductor. When an electrical current flows through the coil, it creates a magnetic field around it. This magnetic field is constantly changing due to the alternating current (AC) passing through the coil. As a result, an EMF is induced in the coil according to Faraday's law of electromagnetic induction. 3.
