Electric bell Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12753
The Electric Bell by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate the working principle of electromagnetism, electric circuits, magnetic effects of electric current, and make-and-break contact mechanism. It is widely used in school science laboratories, college physics labs, STEM classrooms, and educational training institutes.
This apparatus helps students understand how electrical energy is converted into sound energy. When current flows through the coil, it produces an electromagnet that attracts the armature. This movement causes the hammer to strike the gong and also breaks the circuit. The process repeats rapidly, producing a continuous ringing sound.
The Electric Bell is ideal for classroom demonstrations and student practicals related to electric current, electromagnets, circuit operation, magnetic fields, and energy conversion. Its simple construction and clear working mechanism make it an important teaching aid for physics and general science education.

Frequently Asked Questions
- What is an Electric Bell used for?
An Electric Bell is used to demonstrate electromagnetism, electric circuit operation, and conversion of electrical energy into sound energy.
- How does an Electric Bell work?
When electric current passes through the coil, it acts as an electromagnet and attracts the armature. This causes the hammer to strike the gong and also breaks the circuit. The action repeats rapidly to produce ringing sound.
- Is this apparatus suitable for school laboratories?
Yes, it is suitable for school science labs, college physics labs, STEM classrooms, and educational institutions.
- What power supply is required?
The Electric Bell generally works with a suitable low-voltage DC power supply or battery as per the model design.
- What scientific principle does it demonstrate?
It demonstrates the magnetic effect of electric current, electromagnetism, circuit making and breaking, and energy conversion.
- Can students observe the working mechanism?
Yes, many educational electric bell models have an open or mounted design so students can observe the coil, armature, contact screw, hammer, and gong.
- What safety precautions should be followed?
Use only the recommended low-voltage supply, avoid short circuits, keep hands dry while connecting wires, and operate the apparatus under teacher supervision.
- Why does the bell ring continuously?
The bell rings continuously because the circuit is repeatedly made and broken by the movement of the armature, causing rapid hammer strikes on the gong.
