In an automotive plug ignition coil core system (16) and method, a first core (16) is formed of stacked laminations each of which comprises a segmented lamination strip (16A) folded around to create an enclosed loop shape. Each strip has four segments (17, 18, 19 ,20) and a hinge web (21, 22, 23) is provided between first and second, second and third, and third and fourth segments. A grain direction of electrical steel runs lengthwise in each of the segments. A second core inside of the closed loop first core is formed of a plurality of stacked laminations, each lamination having a grain direction of electrical steel running lengthwise. |
