Magnetic-field induced electronic anapolesin small molecules

A magnetic field induces toroidal vortices and associated orbital anapolemoments in the electron cloud of the -OH anion and of Li2 and H2CO molecules, as shown via three-dimensional models of the quantum-mechanical current density and corresponding stagnation graphs. The presence of the induced anapoles is proved via closed continuous stagnation loops of the quantum-mechanical current density vector field.
