Question
Which of the following is constructed on the principle of electromagnetic induction?
- Galvanometer
- Transformer
- Generator
- Both b and c
Hint:
The generators and transformers are constructed on the basis of the principle of electromagnetic induction.
The correct answer is: Both b and c
Both b and c
i.e. The generators and transformers are constructed on the basis of the principle of electromagnetic induction.
- Electromagnetic induction is the induction of current by a relative motion between the coil and the magnet.
- The generators and transformers are constructed with the principle of electromagnetic induction.
- Faraday discovered that the flow of electric charges could be induced by moving an electrical conductor in a magnetic field.
- This is termed electromagnetic induction.
