A is a highly sensitive electromechanical instrument used to detect the presence, direction, and magnitude of small electric currents in a circuit. Derived from the name of Italian researcher Luigi Galvani, it serves as the foundational mechanism behind many classic analog measuring devices. ⚡ Working Principle
The functioning of a galvanometer is based on . When an electric current passes through a conductor placed inside a magnetic field, the conductor experiences a mechanical force. In a moving coil galvanometer, the current passes through a suspended coil, generating a magnetic field that interacts with the field of permanent magnets. This creates a twisting force or torque , rotating the coil and moving an attached pointer across a calibrated scale. 🛠️ Key Components galvanometer
