Trigger And The Mel Gibson Effect
Electric motor Definition, Types, & Facts Household uses (like in washing machines, dishwashers, fans, air conditioners and refrigerators ) of electric motors reduced heavy labor in the home and made higher standards of convenience, comfort and safety possible. Today, electric motors consume more than half of the electric energy produced in the US. The invention of the electrochemical battery by Alessandro Volta in 1799 made possible the production of persistent electric currents. Hans Christian Ørsted discovered in 1820 that an electric current creates a magnetic field, which can exert a force on a magnet. Applications include industrial fans, blowers and pumps, machine tools, household appliances, power tools, vehicles, and disk drives. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. They are also used in maglev trains, where
