electromagnetic forces

Forces resulting from electrical charges that either attract or repel particles. Particles with opposite charges are attracted to each other, while particles with similar charges repel each other. For example, a particle with a positive charge is attracted to a particle with a negative charge but is repelled by another particle with a positive charge.
