Fifth, they always form a closed loop around the magnet moving from north to south. Surround the source and "catch" all of the flux. This is a positive divergence, and the point is a source of flux, like a hose. While the total amount of the flux produced by a magnet is important, we are more interested in how dense or concentrated, the flux is per unit of cross-sectional area. A flux is the value of the surface integral of any vector field. Faraday noticed that when a wire moves through magnetic flux density the magnetic flux linkage remains the same but there is no current. The direction of current flow does not affect what the current does. The flux pattern for this magnetic field would be number of concentric circle perpendicular to the detection of current. 5 Mutual inductance.
