Magnetostatics – Magnetic Flux Density
... We cannot saw the magnet in half to isolate the north and the south poles; as Figure shows, if you saw a magnet in half you get two magnets. Put another way, you cannot isolate a magnetic pole. From this characteristic of magnetic fields, it is easy to see that the net magnetic flux passing through ...
