🔍 Key Concepts

• Behavior of magnetic circuits compared to electrical circuits • Meaning of reluctance, permeability, hysteresis, and eddy currents • Analogy between resistance to current flow and opposition to magnetic flux

💭 Think About

• Which term describes how reluctant a material is to let magnetic flux pass through it? • Which of these choices refers to a property that helps magnetic flux (the opposite of opposition)? • Which terms are related to losses over time or circulating currents rather than simple opposition to flux?

✅ Before You Answer

• Match the definition: opposition to magnetic flux in a magnetic circuit, not electrical current • Identify which option is the magnetic equivalent of electrical resistance • Eliminate terms that describe time lag in magnetization or induced circulating currents in conductors
