The galavanometer consists of a coil with 10 te many turns wound on a cylinderical soft iron core When a current flows through the coil a torque acts on it This torque is given by t NIAB The magnetic torque NIAB tends to rotate the coil by angle o A spring provides a counter torque ko that balances the magnetic torque The current sensitivity of the galvanometer is the deflection per unit current Statement 1 Two galvanometers with identical construction but one with core of greater permeability will have lesser current sensitivity Statement 2 Greater is the permeability of iron core greater is magnetic field 1 Statement I is true Statement II is true Statement II is the correct explanation of Statement I 2 Statement I is true Statement II is true Statement II is not the correct explanation of Statement I 3 Statement I is true Statement II is false 1 Statement I is false Statement II is true NIABUS al R 13 2 1 NIA fun 2 3 4 fur
