In IB Physics First Assessment 2016, magnetic effects of electric currents is a subtopic of Topic 5, electricity and magnetism. This subtopic has the following understandings associated with it.
- Magnetic fields
- Magnetic force
In this part of the analysis, I am particularly interested in “What is the frequency distribution of the questions concerning magnetic effects of electric currents understandings?”
Frequency distribution of questions by magnetic effects of electric currents understandings for HL
Between 1999-2023
For the entire dataset for HL, magnetic fields accounted for only about one-fifth of the questions, whereas magnetic force accounted for four-fifths.
Figure 1
Between 2016-2023
Between these years, the distribution of questions is identical to the entire dataset.
Figure 2
Frequency distribution of questions by magnetic effects of electric currents understandings for SL
Between 1999-2023
The distribution for the entire SL dataset is almost identical to HL. Magnetic force is assessed more heavily than magnetic field.
Figure 3
Between 2016-2023
Between these years, magnetic force is even more emphasized. Almost nine out of ten questions came from magnetic force.
