Induced Current
The steady current in the coil `C_2` as shown below produces a steady magnetic field. As coil `C_2` is moved towards the coil `C_1`, the galvanometer shows a deflection. This indicates that electric current is induced in coil `C_1`. When `C_2` is moved away, the galvanometer shows a deflection again, but this time in the opposite direction. This deflection is based upon the Faraday’s law of electromagnetic induction.
What will be the direction of deflection of galvanometer, when `C_2` is moved away?
Options:
(a) Same direction
(b) Opposite direction
(c) No deflection
(d) Neither ( a) nor ( b)
