I would add, as you note- the physics governs why the right hand screw rule in electrical engineering- governs the more centrepedal requirement
for biology ( implosion / explosion
for the same reason the south magnetic pole (centripedal) speeds healing by increasing pain / focus/ centripedal force..
(north reduces pain AND healing rate.. centrifugal..
