(i) What kind of change can we observe in the Galvanometer when the current in the Solenoid coil is
switched off?
(ii) What change do we observe in the galvanometer when a current is passing through the solenoid
coil and the coil is displaced laterally with respect the coil?
(iii) What change do we observe in the galvanometer if the displacement of the Solenoid is faster?
(iv) What change do we observe in the galvanometer if the current in the Solenoid coil is changed?
(v) What is the definition of Faraday's law of induction?
Answers
Answer:
Answer .i
Current flows in the coil of the solenoid in the clockwise direction and the galvanometer shows deflection towards the left.
Explanation:
Answer .iii
If the solenoid coil is moved towards or away from the coil, we see a deflection in the Galvanometer (fig 4.16c) Also, the faster is the displacement of the solenoid. larger is the deflection of the Galvanometer pointer.
Answer .iv
If the current in the solenoid coil is changed, a current is produced in the coil or if Galvanometer Battery the solenoid coil is moved towards the coil, then also a current is produced in the coil 4.16 c) When a current passing through the solenoid coil and the Faraday's law of induction: solenoid coil is displaced ...
Answer .v
Faraday's law of induction (briefly, Faraday's law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon known as electromagnetic induction.
