🔍 Key Concepts

• Hysteresis loss is related to repeated magnetization and demagnetization of the transformer core each cycle • This loss depends strongly on the magnetic properties of the core material and its B-H (flux density vs. magnetizing force) curve • Construction choices like laminations mainly affect eddy current losses, not hysteresis losses

💭 Think About

• Which choice directly changes the magnetic characteristics of the core material so that less energy is lost each cycle of magnetization? • Think about the main difference between eddy current loss and hysteresis loss—which construction method is used specifically for eddy currents? • Which options mostly affect copper (I²R) losses or voltage level rather than the magnetic behavior of the core?

✅ Before You Answer

• Identify which option is specifically aimed at improving the core material’s magnetic properties (narrower hysteresis loop). • Eliminate any option that is primarily used to reduce eddy current losses rather than hysteresis. • Eliminate options that mostly change copper losses (I²R) or system voltage instead of the core’s magnetization behavior.
