Moving Coil Galvanometer-

 

Moving coil galvanometer operates on Permanent Magnet Moving Coil (PMMC) mechanism and was designed by the scientist d’Arsonval. Moving coil galvanometers are of two types-

(I) suspended coil

(II) pivoted coil type or tangent galvanometer

 

 

Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque. This torque tends to rotate the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum.

 

All the best!
