Solution
(a) To obtain a large deflection, one or more of the following steps can
be taken:  (i) Use a rod made of soft iron inside the coil C2, (ii) Connect
the coil to a powerful battery, and (iii) Move the arrangement rapidly
towards the test coil C1 (b) Replace the galvanometer by a small bulb, the kind one finds in a
small torch light The relative motion between the two coils will cause
the bulb to glow and thus demonstrate the presence of an induced
current In experimental physics one must learn to innovate
