In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with space and time. Probability currents are analogous to mass currents in hydrodynamics and electric currents in electromagnetism. As in those fields, the probability curre… WebΦ = EA If the normal to the area is at an angle θ to the direction of the field then the flux through the area A is given as Φ = EACos θ Zero Flux: No electric field lines will pass through a surface when it placed parallel to the electric …
WebAug 4, 2011 · -- Assuming the circuit to be complete, I get a current flowing through the coil whose value is current = flux linkage / coil inductance As the magnet moves away from the center, the flux linkage decreases. However the magnitude of flux linkage is positive -- From the previous equation, current is still positive since flux linkage is positive
