Answer:
(a) When North pole is pushed
into the coil, a momentary deflection is observer in the galvanometer. This deflection
indicates that a momentary current is produced in the coil.
The direction of current in the
coil is anti-clockwise. (1)
(b) When the magnet is held at
rest, there is no deflection in the galvanometer. It indicates that no current
is produced in the coil in this use. (1)
(c) In pulling the magnet out of
the coil, a deflection in opposite direction is observed. It indicates that the
current produced in the coil is in opposite direction. (1)
