Flat coil forming method and inductor

The invention relates to the technical field of inductors, in particular to a flat coil forming method and an inductor, and the method comprises the steps that an enameled flat copper wire is pulled out of an enameled flat copper wire roll and is bent and formed through a bending machine; electromagnetic induction heating is carried out on the enameled flat copper wire while the bending machine bends the enameled flat copper wire; the enameled flat copper wire comprises a flat copper wire, an enameled layer and at least two iron-containing copper alloys, the cross section of each iron-containing copper alloy is circular, and the enameled layer is coated on the outer surface of the flat copper wire; the iron-containing copper alloys are arranged in the flat copper wire, and the two iron-containing copper alloys are embedded in the arc-shaped edges of the two sides of the flat copper wire; induction heating is carried out while the bending machine is used for bending, the iron-containing copper alloy and the ar
