Question

How is this phenomena of magnetic induction related to electrical power generation? What is one electrical power generation method that does not use magnetic induction?

Answer 1

usually, electric power is generated by converting mechanical energy into electrical energy. we use generators for this purpose. the generator contains a fixed magnet and a rotating coil. the coil is rotated by mechanical work( by water flow in the dam, by the wind in the windmill, etc ). while the magnetic flux (flux of fixed magnets) linked with this coil is changing, there is an emf will induce across coil according to faradays law. this development of emf due to change in magnetic flux is called magnetic induction.

in batteries, we produce electric power through chemical reaction.
