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.
When the coil `C_2` is held fixed and `C_1` is moved , then
Options:
(a) same effects are observed, i.e. current is induced in coil `C_1`
(b) no current is induced in coil `C_1`
(c) number of magnetic field lines through `C_1` do not change
(d) current in coil `C_2` increases drastically
