Statement -1 : The sensitvity of a moving coil galvanometer is increased by placing a suitable magnetic material as a core inside the coil.
Statement - 2: Soft iron has a high magnetic permeability and cannot be easily magnetized or demagnetized.

Options

A. Statement -1 is true Statemetn -2 is true, Statement -2v is a correct explation for Statement -1 .
B. Statement -1 is true Statemetn -2 is true Statement-2 is not explation for Statement -1
C. Statement-1 is true Statement -2 is false
D. Statement -1 is false Statement -2 is true

Answer

`C`

Explanation

Placing a soft iron core inside the coil makes the magnetic field radial which increases the torque acting on the coil due a given current flowing in the coil The sensitivity increase because for the same current the deflection of the coil is more when a core is inserted inside the coil Statement 1 is true and Statement -2 is false coil Statement-1 is true and Statement-2 is false .
