CUET Preparation Today
Moving coil galvanometer operates on a Permanent Magnet Moving Coil(PMMC) mechanism and was designed by the scientist D'arsnoval. It is of two types:
Its working is based on the fact that when a current carrying coil is placed in a magnetic field, it experiences a torque that rotates the coil about its axis of suspension in such a way that the magnetic flux passing through the coil is maximum. |
What is true about the deflection in a moving coil galvanometer? |
directly proportional to the torsional constant of the spring directly proportional to the number of turns in the coil inversely proportional to the area of the coil inversely proportional to the current in the coil |
directly proportional to the number of turns in the coil |
deflection = NABI/k |
