What is PMMC?

PMMC stands for Permanent Magnet Moving Coil. The instruments which use a 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 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.

How to Calculate Angle of deflection of PMMC?

Angle of deflection of PMMC calculator uses Angle of Deflection=(Number of Turns*Flux Density of Coil*Length*Width*Current in Coil)/K (spring) to calculate the Angle of Deflection, The Angle of deflection of PMMC gives the angle at which both torques are balanced. It is the indicating parameter. Angle of Deflection and is denoted by θ symbol.
