Final answer:
To produce current mechanically, a magnetic field, conductive wire loops, and a rotational mechanism are essential. These components work together in electric generators and motors to convert between mechanical work and electrical energy.
Step-by-step explanation:
To produce current mechanically in devices such as electric generators and motors, three primary components are needed:
-
This process converts mechanical work into electrical energy. In an electric motor, electrical energy is used to create a rotating magnetic field, which then exerts a torque on the wire loops attached to a shaft, converting the electrical energy back into mechanical work.
