In working of moving coil galvanometer (select the correct alternatives) Eddy current help in achieving equilibrium of coil faster. Cylindrical soft iron core helps in make magnetic field radial & increasing strength of torque on coil. Parallex error needs to minized while taking measurement. Marking on scale are equally spaced for equal change in current.
