Inquiry question: How are electric and magnetic fields related?
Students:
● describe how magnetic flux can change, with reference to the relationship 𝛷 = 𝐵∥𝐴 = 𝐵𝐴cosθ (ACSPH083, ACSPH107, ACSPH109)
● analyse qualitatively and quantitatively, with reference to energy transfers and transformations, examples of Faraday’s Law and Lenz’s Law 
including but not limited to: (ACSPH081, ACSPH110)
– the generation of an electromotive force (emf) and evidence for Lenz’s Law produced by the relative movement between a magnet, straight conductors, metal plates and solenoids
– the generation of an emf produced by the relative movement or changes in current in one solenoid in the vicinity of another solenoid
● analyse quantitatively the operation of ideal transformers through the application of: (ACSPH110)
● evaluate qualitatively the limitations of the ideal transformer model and the strategies used to improve transformer efficiency, including but not limited to:
– incomplete flux linkage
– resistive heat production and eddy currents
● analyse applications of step-up and step-down transformers, including but not limited to:
– the distribution of energy using high-voltage transmission lines
