Magnetism And Electricity

Points out the relationship between electricity and magnetism and shows how this relationship is used in the design of electric motors and generators. Defines electric current, demonstrates how a magnetic field exerts force on an adjacent magnetic field, and explains the principle of the electric generator. Reiterates that electrons in motion are always surrounded by magnetic fields and that magnetic fields in motion always force free electrons to move., Points out the relationship between electricity and magnetism and shows how this relationship is used in the design of electric motors and generators.
