See main: Human molecular spin, human molecular orbitalIn addition issue of field particle exchanges between individual humans, which constitutes the mechanism of force in the attachment or detachment of human chemical bonds, there is the issue of field particle exchanges between the earth and humans, i.e. between the earth molecule and individual human molecules attached to the earth's surface.  In short, whenever a charge moves, it creates a magnetic field that curls around the axis of its trajectory and when an external magnetic field is applied to a charge it causes the charge to curl in motion around the axis of the magnetic field.
