Answer: A dynamo falls under the branch of physics known as electromagnetism or electromagnetic physics. Electromagnetism is the study of the relationship between electricity and magnetism and how they interact with each other.
A dynamo is a device that converts mechanical energy into electrical energy using the principles of electromagnetism. It typically consists of a rotating coil of wire (armature) within a magnetic field. As the coil rotates, the magnetic field induces an electric current in the wire through electromagnetic induction.
The operation of a dynamo involves the application of various electromagnetic principles, such as Faraday's law of electromagnetic induction and Lenz's law. Understanding the behavior and functioning of dynamos requires knowledge of electromagnetism, including the principles of magnetic fields, electric currents, electromagnetic induction, and the relationship between electricity and magnetism.
Therefore, the study and analysis of dynamos and their operation fall within the domain of electromagnetism, a branch of physics.
