Question

discovery, let us puli
Activity 5
Take a hollow cylindrical pipe of iron and wind a large number of turns of well-
insulated copper wire on it. Clean the two ends of the wire and attach a torch bulb/LED.
to it. Now, take a strong bar magnet and move it rapidly towards the centre of the pipe
(without touching it). What do we observe? We find that the bulb glows. However, it
glows only for a while and stop glowing
as soon as the magnet is stopped. If we
now withdraw the magnet away from
the coil, we find that the bulb again
'glows up' momentarily. We are, thus,
getting electricity through this motion
of the magnet near/through a coil.
