Question
Certain galvanometers have a fixed core made of non-magnetic metallic material. The function of this metallic material is
Select the correct option:
A
to oscillate the coil in magnetic field for longer period of time
B
to bring the coil to rest quickly
C
to produce large deflecting torque on the coil
D
to make the magnetic field radial
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Due to motion of the coil eddy current develops thus bringing the coil to rest.
