Difference between induced emf and generated emf?

In an analogy, Generated EMFs can be considered as the speed or force at which the boat is moving, while Induced EMFs can be considered as a standyby boat with no engine, when the moving boat with an engine passes. Generated EMFs, considered as the boat with an engine, is the voltage which is generated by a source, by which in this case is the engine, while the Induced EMF, considered as the boat with no engine, is affected by the moving boat with an engine, thereby also moving the Induced EMF. In a sense, Generated EMFs have their own source while Induced are only 'moved' by other external forces. Like wise when electrons flow on a wire the ripples or magnetic flux will induce or generate motion on any wire or conductor next to it. That's how Transformers work.
