The reason for having a large number of turns in the coil of a moving coil galvanometer is to--------

  • A make the deflection of the needle proportional to the current
  • B increase the sensitivity of the galvanometer
  • C decrease the magnetic flux produced by the magnet
  • D make the permanent magnet stronger

The correct answer is B. increase the sensitivity of the galvanometer

Sensitivity of a galvanometer increases when number of turns, area of coil and magnetic field increase
