  1. An electromagnetic coil is a device composed of a wire looped around a core, which may be composed of a ferromagnetic material like iron or ferrite or may be air. When electric current flows through the wire, it creates a magnetic field around the coil.

    Consisting of more than one turn, or a loop of wire, a magnetic coil focuses the magnetic field, with every coil of wire supplying a small amount of magnetic field. Adding up all those magnetic fields together creates a stronger vector field that properly functions as a magnet.

    A coil magnetic field refers to the magnetic field generated by an electric current flowing through a coil of wire. This phenomenon is a direct result of Ampere’s law, which states that a current-carrying conductor produces a magnetic field around it. When an electric current passes through a wire, it creates a magnetic field around it.
