Which mechanism reduces transformer core losses when using laminated silicon steel within alternating magnetic fields?

💡 Explanation

When laminated silicon steel is subjected to alternating magnetic fields, the laminations increase electrical resistance across the core section reducing parasitic eddy current formation because eddy currents circulate more easily in solid cores and generate heat. Therefore, the laminated core reduces eddy current losses, rather than increasing hysteresis losses or enhancing domain alignment each influenced by material treatment.
