Why is the shaft of the moving coil tapered?

Question

ITI Exams · Accepted Answer

In a PMMC meter, the moving system is supported on a spindle with tapered and polished ends.
These ends rest in hollow-ground bearings. The primary purpose of this design is to minimize friction.
Reduced friction improves the meter&#8217;s accuracy and sensitivity, enabling it to measure even small currents effectively.
