In this post, let’s look at what’s tested in detail for electromagnetism for O Level physics.
In this chapter, there are a number of explanations and definitions that students should be familiar. You can find the list of definitions for O Level Physics here.
To learn more about this topic on electromagnetism, watch this video where I go through the points in detail in my video here.
Below is a checklist of what you need to know for O Level Physics on the topic current electricity.
Checklist for Electromagnetism for O Level Physics
✓ draw the magnetic field lines due to currents in straight wires and in solenoids
✓ state the effect on the magnetic field when magnitude and/ or direction of current are changed.
✓ application of the magnetic effect of a current in a circuit breaker
✓ describe experiments to show the force on a current-carrying conductor, or on a beam of charged
particles, in a magnetic field,
✓ use Fleming’s Left- hand rule to deduce directions of force, field and current when any two of these quantities are at right angles to each other
✓ describe the field patterns and forces between currents in parallel conductors
✓ describe ways to increase the force experienced by a current- carrying coil in a magnetic field
✓ discuss how an electric motor works
✓ describe the purpose of a split-ring commutator in an electric motor
