The Moving Coil Microammeter is a precision electrical measuring instrument designed to measure very small electric currents in microamperes (µA). It operates on the principle of electromagnetic interaction, where a current-carrying coil placed in a magnetic field produces a deflection proportional to the current flowing through it. It features a sensitive moving coil mechanism, a clear graduated scale, and a pointer for accurate readings. This instrument is widely used in physics laboratories, educational institutions, and scientific experiments for studying electrical circuits, measuring low currents, and demonstrating the principles of electromagnetism. It is an essential apparatus for practical physics experiments and electrical measurements.
