Which statement is correct? Group of answer choices The line integral of magnetic vector potential, A, around any closed path is equal to the total magnetic flux passing through the area enclosed by that path. The algebraic sum of ampere-turn around a closed path in a magnetic circuit is equal to the sum of the ratio of the fluxes over the reluctances. The vector magnetic potential is always perpendicular to the direction of the current. Reluctance increases as the cross section of the ferromagnetic core increases
