Description
[Eternal ringing]: Even when the electromagnet is powered off, the reed automatically springs back to its original place. This causes the current to pass through the electromagnet, attracting the reed again and continuously ringing the iron bell..[Teaching tool]: This kit is perfect for teachers to explain the magnetic effect of current in physics. It requires a DC 3-6V power supply to connect the bell..[Sound production]: With the electromagnet-powered-on, it attracts the reed. As the reed moves towards the magnet, the hammer strikes the iron bell, producing a sound. The moving and static plates contact each other, allowing the current to form athrough the circuit..[Vertical design]: The kit comes with a base for a more intuitive experimental demonstration, allowing students to easily observe all components and learn effectively..[Principle of operation]: When the electromagnet is energized, it becomes magnetic and attracts the armature, causing the dynamic and static contacts to come into contact. This utilizes the magnetic effect of current to make it work.
