Background

Gravitomagnetism – gravitomagnetic field $H$ due to (total) angular momentum $J$ .
Electromagnetism – magnetic field $B$ due to a dipole moment $m$ ...
... or, equivalently, current $I$ , same field profile, and field generation due to rotation.
Fluid mechanics – rotational fluid drag of a solid sphere immersed in fluid, analogous directions and senses of rotation as magnetism, analogous interaction to frame dragging for the gravitomagnetic interaction.
