Gauss's Magnetic Law Gauss's Magnetic Law is very similar to his electric law. It states that the total magnetic flux passing through a closed surface is always zero. That is as much flux enters the surface as leaves it. This is the same as noting that magnets always come in north, south pairs and never alone (monopoles). Even if we break the magnet in two the net magnetic flux is still zero. What would happen if we shrunk the surface so that it only enclosed half of the magnet? Would Gauss's law still hold? |
