Meters with permanent magnets that work with current to move the pointer are called

Right Answer is:

Permanent magnet moving coil type (PMMC) meters

SOLUTION

  • Meters with permanent magnets that work with current to move the pointer are called Permanent Magnet Moving Coil type (PMMC) meters.
  • PMMC instruments use a permanent magnet to create a stationary magnetic field, and a moving coil interacts with this field when current flows through it, causing the pointer to move.
  • These meters, also known as D’Arsonval meters, are precise instruments primarily used for DC measurements
