ElectromagnetismBefore the 1850s, electricity and magnetism were considered unrelated. James Clerk Maxwell proved them to be linked in the single phenomenon of electromagnetism. Maxwell`s equations describe how electric and magnetic fields are generated by charges, currents, and changes of the fields.ChargeElectromagnetism starts with charge. Charge is a physical property of subatomic particles, and is based on the number of protons and electrons in a piece of matter. Charge can be positive or negative, and we observe that opposite charges attract, and similar charges repel. The symbol Q often denotes charge.
