The function of the soft iron core in the moving coil galvanometer is:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → To increase the degree of radial field and magnetic field strength
Increase Magnetic field - The soft iron core attracts magnetic line of force, which increases the strength of magnetic field.
Increase magnetic radial field - The soft iron makes the electromechanical field radial, which increases the magnetic field.
