How is magnetism related to AC and DC currents?

Magnetism is fundamentally linked to electric currents through Ampère's law, which states that an electric current produces a magnetic field. In Direct Current (DC), the magnetic field created is steady and constant, while in Alternating Current (AC), the magnetic field fluctuates as the current changes direction. This changing magnetic field in AC can induce electromotive force (EMF) in nearby conductors, a principle used in Transformers and electric motors. Thus, both AC and DC currents generate magnetic fields, but their behaviors differ due to the nature of the current flow.
