Question
The observations made by Faraday from the experiments on electromagnetic induction is (are) that ___________.
I. The deflection in the galvanometer increases when a strong magnet is used.
II. The induced current in the coil is alternating in nature.
- Only I is true
- Only II is true
- Both I and II are true
- Both I and II are false
Hint:
Faraday's observations include that the deflection increases when the magnet is strong and the current forms an alternating current.
The correct answer is: Both I and II are true
The observations made by Faraday from the experiments on electromagnetic induction are both I and II are true.
- Faraday's experiments explain how the relative motion between the magnet and conducting coil induces a voltage or current.
- His observations include that the deflection in the galvanometer increases when a strong magnet is used.
- The induced current in the coil is alternating in nature leading to the induced change in the rate of electromagnetic field
