Correct answer to the question. Draw a labelled diagram of a moving coil galvanometer Explain the principle on which it works. B Explain the term eddy currents and state two devices in which the currents are applied.

The reason is magnetic flux is maximum through coil only if the face of coil is normal to the flux meaning the area vector of the face of coil must be parallel to the flux always which you can understand from the following equation for torque ie T BI N Acosa where a is the angle between area vector and magnetic flux so you must.
