Quote In the simplest terms, a motor works by current moving through a magnetic field, creating mechanical movement (spinning a rotor).Quote
Can some one explain this better.
Quote A dynamo works in reverse – mechanical movement spins a magnetic field, creating current. Quote
sorry I do not know how a dynamo works or how a generator works.

A motor works by running current through a coil that creates an electromagnet that attracts an arm. A DC motor uses a make and break circuit to keep the arm rotating. An AC motor uses a commutator to change the direction of the attraction, as the direction of the power changes, so that the arm keeps rotating. This rotational motion is used to cause something to rotate such as a saw blade, or through gears change the direction of the motion.
A generator uses outside motion such as steam, water power, moving water, wind, to move a coil past a magnet. This movement causes a current to run in the coil , this is electricity.
