Electric Bell

Original price was: $ 14.88.Current 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.

Induction coil

An induction coil is an electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. It consists of two coils of wire—primary and secondary—wound around a common iron core. When current passes through the primary coil, it creates a magnetic field that induces a high voltage in the secondary coil. Induction coils are essential components in ignition systems, spark generation, and scientific experiments requiring high-voltage pulses. Commonly used in automotive ignition systems, laboratory equipment, and electromagnetic experiments, induction coils enable the conversion of low voltage to the high voltage necessary to generate sparks or initiate other electrical discharges.
