🔍 Key Concepts

• Eddy currents produced in solid metal cores • How laminating (stacking thin insulated sheets of steel) changes current paths in the core • Difference between hysteresis losses and eddy-current losses in transformers

💭 Think About

• Think about what happens when a changing magnetic field passes through a solid block of steel versus many thin insulated sheets of steel. • Ask: which kind of loss depends on circulating currents induced in the metal itself, and which depends on the magnetic properties of the material? • Which choice directly involves electric currents flowing in the core material, and which involve magnetic effects or flux patterns instead?

✅ Before You Answer

• Be clear on the definitions of hysteresis vs eddy currents. • Focus on which loss mechanism is reduced specifically by breaking up the core into insulated layers, limiting paths for circulating current. • Check which options refer to changing the material losses in the core versus changing the useful transformer flux.
