William Sturgeon, English physicist, invented the electric motor (born 1783)

William Sturgeon
William Sturgeon was an English electrical engineer and inventor who made the first electromagnet and the first practical electric motor.
Electric motor
An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Laplace force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy.
