What causes the attraction or repulsion between magnetic poles? Answer this from the perspective of an electron. There are two kinds of electric charges: positive and negative. • Charges exert forces on other charges at a distance. • The force is stronger when the charges are closer together. • Like charges repel; opposite charges attract. There are two kinds of electric charge, positive and negative. Interactions of these charges explain the attraction and repulsion Coulomb’s law states that the force between two charged particles varies directly with the product of their charges and inversely with the square of the distance between them. An electron will push the similar charge electron away causing them to spread farther apart. A positively charged (different charge of electron) attracts some of the electrons, causing forcing them to attract. What is the difference in the properties of an electric charge vs. a magnetic charge? you cannot separate charges in magnets, the electron in magnets have north ans south pole.
