3 Questions
Explain the working principle of PMMC?
The working principle of PMMC (Permanent Magnet Moving Coil) is based on the interaction of the magnetic field produced by a permanent magnet and the current-carrying coil, causing the coil to move in response to the force exerted on it due to the interaction of the magnetic field and the current.
Can you provide a simple diagram illustrating the construction of a PMMC instrument?
A simple diagram of the construction of a PMMC instrument would show a permanent magnet, a moving coil with a pointer, and a calibrated scale, with the coil positioned within the magnetic field of the permanent magnet.
Describe the construction of a PMMC instrument.
A PMMC instrument consists of a permanent magnet, a moving coil, a pointer attached to the moving coil, and a calibrated scale. The coil is mounted on jeweled bearings and positioned within the magnetic field of the permanent magnet to allow for free movement.
