Question

(a)
A coil of insulated wire
would be observed if a
is connected to a galvanometer. What
Strong bar magnet with its south pole
towards one face of the coil
(i) moved quickly toward it?
(ii) moved quickly away from it ?
(iii) held stationary near it?
Name the phenomena involved.
Please answer asap​

Answer 1

Answer:

i) galvanometre shows deflection this means that a scrap of current is generated

ii) galvanometre shows deflection in the opposite direction

iii) no deflection in galvanometre because current is not generated

Explanation:

• The phenomenon is electromagnetic induction
• The currebt is generated because of the relative motion between the magnet and coil due to changing magnetic field
• Since there is no motion of magnet in iii) case the current is not generated
