PM Moving Coil

“The Permanent magnet moving coil instrument is the most acrute type for dc measurement.The working principle of these instruments is the same as that of the d’Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and scale.but I want to know why d’Arsonval galvanometer is used PMMC.

The flood of abbreviations and acronyms in the present age is confusing some of us oldies !
