Copper Wire

When electricity passes through a coiled copper wire it creates a magnetic field. This field can interact with either permanent magnets (which saves on electricity costs) or the opposing fields of other electrically charged coils in an electric motor or transformer, to create rotational movement and produce mechanical power. This relationship between electrically charged copper windings and permanent magnets, to create mechanical power, has been the basis for many of the time-saving power tools and electrically powered appliances we take for granted today.

Permanent Magnets, copper wire coils and batteries for a power source are commonly used in experiments and classroom demonstrations to explain how electric propulsion is generated inside electric motors.
