Electromagnetism:The Electric Field
-Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

-Magnetic fields are produced by electric
currents, which can be macroscopic
currents in wires, or microscopic currents
associated with electrons in atomic orbits.
7. -similar poles repel while opposite pole
attracts.

8. Electric motors involve rotating coils of wire which are
driven by the magnetic force exerted by a magnetic field
on an electric current. They transform electrical energy
into mechanical energy.
