Galvanometer

Galvanometer – Precision Instrument for Measuring Electric Current

A Galvanometer is a highly sensitive instrument designed to detect and measure small electric currents. It operates based on the principle of electromagnetic deflection, where an electric current passing through a coil generates a magnetic field that interacts with a permanent magnet, causing the needle to deflect. This deflection is proportional to the current, allowing for precise readings.

Key Features

✔ Highly Sensitive Detection – Measures extremely small electric currents with high accuracy.
✔ Electromagnetic Deflection Mechanism – Utilizes coil movement in a magnetic field for precise readings.
✔ Analog Dial Display – Provides clear and accurate needle-based measurement.
✔ Durable & Stable Construction – Made from high-quality materials to ensure long-lasting performance.
✔ Portable & Compact Design – Lightweight and easy to use for laboratory and educational purposes.

Common Uses

🔹 Physics & Electrical Experiments – Used in laboratories to demonstrate electrical principles.
🔹 Circuit Testing & Research – Helps in detecting small currents in electronic circuits.
🔹 Educational Purposes – A valuable tool for students and researchers studying electromagnetism.
🔹 Component of Advanced Meters – Forms the basis of ammeters and voltmeters in electrical measurements.

Types of Galvanometers

🔸 Moving Coil Galvanometer – Uses a coil suspended in a magnetic field for high sensitivity.
🔸 Ballistic Galvanometer – Specially designed to measure short-duration charge pulses.
🔸 Mirror Galvanometer – Uses a mirror and light beam reflection for precise deflection measurement.
