Software simulator for point charges & conductors. Imo there's no satisfyingly deep explanation for why opposite charges attract and like charges repel. Similar to how magnets attract, positively charged ions draw their electrons closer to them because they contain stronger positive charges. Coulomb's law may look somewhat familiar, because it has a lot in common with Newton's law of gravitation: Like gravitational force, whose magnitude increases with mass, electric force magnitude increases with the magnitude of the charges. If you have any sources explaining clearly, I would also appreciate that. For electromagnetic interactions are needed minimum two different types of particles. When a negatively charged object is brought closer to a neutral object the protons . It may not look gauge invariant at first, but after adding gauges, one sees it is indeed gauge invariant. It took scientists a long time to discover what lay behind these two types of charges. The charges of two objects will attract one another if one object has positive charges and the other has negative charges. First, electrons repel one another.

Like Charges Repel and Unlike Charges Attract Each Other Why do opposite charges attract and like charges repel? - Physics Forums Similar to this, when two particles with the same charge are close to one another, they become more unstable and attempt to repel one another in order to become more stable. Thus, since each electroscope carries the same charge, when they are moved towards each other, they repel due to the fact that they are of like charge. By suspending pieces of tape from a straw, you can build an electroscopea device that detects electrical charge. How does the Electric field apply a force? Figure 2 . However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law. A neutral object will draw both positive and negative charges. Why Do Like Charges Repel And Opposite Charges Attract? It seems to support my idea of why like charges repel. The charges on two objects will attract each other if one of the charges is positive and the other is negative. Physics doesn't have at the moment a theory on a subatomic level (below the level of virtual photons) describing how the interaction between charged particles works.
