Electric Bell – Double Gong, 75 mm (KS3+)

This Electric Bell is a simple, durable double‑gong bell ideal for KS3 and above, perfect for demonstrating basic electrical circuits, electromagnets, and switching mechanisms in physics lessons. With its classic dome‑style housing and detachable cover, students can clearly observe the internal components and understand how the hammer, armature, and electromagnet interact to produce continuous ringing.

The unit features threaded metal terminals for quick and secure connection to low‑voltage power supplies, making it easy to incorporate into classroom circuit setups. With an approximate diameter of 75 mm, this compact bell is robust enough for repeated student use and clear enough for front‑of‑class demonstrations.
