👉 In physics, "superefflux" is a term used to describe an electromagnetic field that has a negative pressure gradient. This means that as the electric field (the force per unit charge) increases, the magnetic field (which opposes this change in electric field) decreases. The direction of superefflux is opposite to the direction of a steady flow of electric current. For example, suppose there's an alternating current (AC) flowing through a conductor and the AC current has a negative pressure
