In a dynamo, electric current is produced using the principle of?

Aelectromagnetic radiation

Belectromagnetism

Celectromagnetic induction

Delectric conduction

Answer:

C. electromagnetic induction

Read Explanation:

  • A dynamo uses the principle of electromagnetic induction to produce electric current.

  • Electromagnetic induction is the process where a changing magnetic field induces an electromotive force (EMF) in a conductor.

  • Dynamo or electric generator is used to generate electrical energy from mechanical motion.

  • It is based on the principle that when there is a motion of a conductor within a constant magnetic field, an electromotive force is generated in it due to which a current starts flowing in it.

  • This takes place due to change in magnetic flux passing through the conductor and hence a current is induced in it which can be used as dynamo’s output.
