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

Aelectromagnetic radiation

Belectromagnetism

Celectromagnetic induction

Delectric conduction

Answer:

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.
