What phenomenon occurs when an electric current flows through a conductor?

When an electric current flows through a conductor, it creates a magnetic field around the conductor. This phenomenon is a manifestation of electromagnetism and is described by Ampère’s circuital law. The magnetic field produced by the current influences nearby magnetic materials and can induce forces on other conductors or magnets. Additionally, the interaction between the magnetic field and the current-carrying conductor can lead to mechanical effects, such as the generation of a force that causes the conductor to experience motion. This relationship between electric currents and magnetic fields is fundamental to the understanding of electromagnetism.
