What is PMMC?

PMMC stands for Permanent Magnet Moving Coil. The instruments which use the permanent magnet for creating the stationary magnetic field between which the coil moves are known as a permanent magnet moving coil or PMMC instruments.

How does torque in PMMC work?

When a current flows through the coil, it generates a magnetic field that is proportional to the current in the case of an ammeter. The deflecting torque is produced by the electromagnetic action of the current in the coil and the magnetic field. When the torques are balanced, the moving coil will stop and its angular deflection represents the amount of electrical current to be measured against a fixed reference, called a scale.
