摘要：
An electromagnetic coil which may be employed as an ignition coil for an internal combustion engine is disclosed. The electromagnetic coil includes a lower voltage winding portion and a higher voltage winding portion. The lower voltage winding portion is wound around a spool and includes a plurality of winding layers overlapped with each other and inclined at a given angle to the length of the spool. Each of the winding layers includes a collection of turns made up of a leading portion of wire. The higher voltage winding portion is wound around the spool adjacent the lower voltage winding portion and includes a plurality of winding layers overlapped with each other and inclined at a given angle to the length of the spool. Each of the winding layers includes a collection of turns made up of a trailing portion of the wire.
