Can anyone explain Maxwells 4 equations in simple terms, which even a middle school kid can understand?
I’ll try. The first equation basically say that is you look at an electric field entering a volume, like a box, and you look at it leaving the volume, any difference in its strength is due to thae amount of electrical charge inside the volume. So if there is no charge present, the electric field will not change value. Another way to look at this is if there is a charge in the volume, there will be an electric field present outside the voulme due to the charge. So the first equation relates charge to electric field strength. The second equation involving the electric field is a bit more esoteric. It says that unless there is a magnetic field that changes strength over time, the electric field doesn’t curve around itself, that is, it always begins and ends on an electric charge. If there is a time varying magnetic field that is coupled to the electric field by moving charges, then the second equation says the electric field can loop back on itself. The third equation is like the first eq
