When magnetic current flows through a wire, the hammer is drawn to the bell. When the current is disconnected, the magnet loses its attraction. Discover the working principle of the electromagnet and its application.


Try the Bell Experiment:



The Bell uses a magnetic current to activate the hammer to hit the bell. Disconnect the circuit and the hammer doesn't hit the bell.


This product uses magnetic current through the magnetic, the hammer over the bell. When you disconnect the circuit, the magnet loses its magnetism, the hammer is bounced back, the circuit is closed, and this cycle repeats continuously. The sound helps students understand the working principle of the electromagnet and its application.


Fundamental principles:

- Open Circuits

- Closed Circuits

- Electromagnet

- Electric Bell Theory

- Electromagnetic relay
