Electric Bell
Original price was: $ 14.88.$ 14.73Current price is: $ 14.73.
Electric Bell is a mechanical signaling device that produces a ringing sound when energized by an electric current. It typically consists of an electromagnet, an armature, a striker, and a bell or gong mounted on a sturdy base. When an electric current passes through the coil of the electromagnet, it attracts the armature, causing the striker to hit the bell and produce sound. The armature then releases due to a spring mechanism, allowing repeated strikes as long as the circuit is closed. Electric Bells are widely used in educational laboratories, industrial setups, and domestic applications for alerting, signaling, and notification purposes. The device is valued for its reliability, simple design, and ease of integration into electrical circuits. In physics education, the electric bell demonstrates fundamental electromagnetic principles such as electromagnetism, magnetic attraction, and electric circuit operation.
