A dynamo produces an electric current. It is based on the principle:

1. magnets have attractive property
2. conductors carrying current behave like magnets
3. electromagnetic induction
4. none of these

Correct answer: electromagnetic induction

Solution

A dynamo works because moving a conductor in a magnetic field, or changing the magnetic field around a conductor, induces an emf and current. That phenomenon is electromagnetic induction.
