The quantity to which the turning force of a d’Arsonval meter movement proportional to?

Answer to Problem 1RQ

The turning force of a d’Arsonval meter movement is proportional to the strength of the magnetic field developed in the current carrying coil.

Explanation of Solution

Description:

The underlying principle behind operation of the d’Arsonval meter movementis that like magnetic poles repel each other. The turning force of depends on the repulsion of magnetic fields. A magnetic field is created around the coilas current passes through it.

The flow of current is such that the polarity of the permanent magnet and that of the magnetic pole created around the coil is the same. As like magnetic poles repel each other, the coil is deflected away from the pole of the magnet. A spring provides the damping movement to the turning of the coil. The turning distance against the spring is proportional to the strength of the magnetic field developed in the current carrying coil.

Conclusion:

The quantity on which the turning force of a d’Arsonval meter movement is dependant has been explained.
