- Earnshaw's_theorem abstract "Earnshaw's theorem states that a collection of point charges cannot be maintained in a stable stationary equilibrium configuration solely by the electrostatic interaction of the charges. This was first proven by British mathematician Samuel Earnshaw in 1842. It is usually referenced to magnetic fields, but was first applied to electrostatic fields.Earnshaw's theorem applies to classical inverse-square law forces (electric and gravitational) and also to the magnetic forces of permanent magnets, if the magnets are hard (the magnets do not vary in strength with external fields). Earnshaw's theory forbids magnetic levitation in many common situations.If the materials are not hard, Braunbeck's extension shows that materials with relative magnetic permeability greater than one are further destabilising, but materials with a permeability less than one- diamagnetic materials- permit stable configurations.".
