In IB Physics First Assessment 2016, electromagnetic induction is a subtopic of Topic 11, electromagnetic induction. This subtopic has the following understandings associated with it.
- Electromotive force (emf)
- Magnetic flux and magnetic flux linkage
- Faraday’s law of induction
- Lenz’s law
In this part of the analysis, I am particularly interested in “What is the frequency distribution of the questions concerning electromagnetic induction understandings?”
Frequency distribution of questions by electromagnetic induction for HL
Between 1999-2023
For the entire dataset for HL, more than two-thirds of the questions came from electromotive force and magnetic flux and magnetic flux linkage. Lenz’s law was relatively less emphasized.
Figure 1
Between 2016-2023
Faraday’s law of induction and emf between these years accounted for more than half of the questions. Magnetic flux and magnetic flux linkage accounted for more than one-third of the questions. Lenz’s law was again the least emphasized understanding in this subtopic.
