Intensity of the gravitational field is proportional to M/r2, its range is long, its strength is weak, and the direction of the field lines is toward the center of the mass. Electric Fields have a point charge as their source, a field intensity proportional to Q/r2, a short range, a strong strength, and a field line direction toward the center of charge. Magnetic fields include the following characteristics: no point source; dipole required; field intensity proportional to: n/a because there is no point source; short range; strong; and field line direction dependent on the motion of a charge that produces the magnetic field lines. If not, they travel south to north.
