An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side.he magnetic field of electromagnets in the general case is given by Ampere's Law : which says that the integral of the magnetizing field H around any closed loop of the field is equal to the sum of the current flowing through the loop.
