It has become clear from earlier discussion that the lamination of cores is needed to restrain eddy currents and to allow rapid flux penetration into the bulk of a core. Such lamination is only efficacious if adequate insulation is maintained between layers. The application of a suitable coating can ensure that insulation between sheets is adequate. There are other motivations for having a coating present.
