Gauss's law for magnetism

Gauss's Law for Magnetism is a scientific rule that describes how magnetic fields work. It is named after the scientist Carl Friedrich Gauss. The rule states that the total magnetic field at a point in space is equal to the sum of all the magnetic field lines that start and end at that point. This means that when two magnets are placed close to each other, the magnetic fields of each will combine together, creating a stronger magnetic field. To put it simply, the more magnetic field lines at a point, the stronger the magnetic force.
