The Bell Double Coil is a key element of physics experiments, especially those studying electromagnetism and magnetic fields. Its two coils are closely wound, demonstrating the concept of electromagnetic induction. When electricity passes through one coil, it generates a magnetic field that triggers a current in the next, showing the connection between electricity and magnetism.

This apparatus provides an interactive experience for physics laboratories, demonstrating core principles like Faraday's Law and the behavior of magnetic fields in an engaging way.

Coil diameter: 65mm diameter

Product Code: SE.MS0028-01

*Built-in gong powered by a 3V source
