A Permanent Magnet Moving Coil PMMC meter also known as a DArsonval meter or galvanometer is an instrument that allows you to measure the current through a coil by observing the coils angular deflection in a uniform magnetic field A PMMC meter places a coil of wire between two permanent magnets to create a stationary magnetic
PMMC Instrument The term PMMC is the short form of permanent magnetic moving coilThese instruments use permanent magnets to create the stationary magnetic field in the coils Then it is used with the moving coil that is connected to the electric source for generating deflection torque according to the Fleming lefthand rule theory Working principle of PMMC Instrument
Learn about the PMMC instrument a type of galvanometer that measures DC current or voltage using a permanent magnet and a moving coil See the diagram the torque equation the errors and the advantages of this instrument

Learn how PMMC instruments work on the principle of permanent magnet moving coil and measure DC current or voltage See the diagram and components of PMMC instruments such as coil magnet spring damping pointer and scale
The schematic of PMMC is shown in the following figure When the current to be measured is applied to the moving coil terminals placed in the magnetic field The coil experience a torque and starts moving

The PMMC instrument is shown in the below images The moving coil is either rectangular or circular in shape It has number of turns of fine wire The coil is suspended so that it is free to turn about its vertical axis
The construction of a Permanent Magnet Moving Coil PMMC instrument is shown in the figure below The moving coil is either rectangular or circular in shape It has a number of turns of fine wire The coil is suspended so that it is free to turn about its vertical axis
The basic PMMC instrument diagram is shown below A rectangular coil of thin wire with some turns is wound on an aluminum frame which has an iron core inside It is placed between the Ushaped permanent magnet poles which are made up of Alnico magnetic alloy
When a current carrying conductor is placed in a magnetic field the force is produced on the conductor coil This force tends to move the coil in the space Fig 1 shows constructional details of PMMC instruments with different constructions of permanent magnets
