Magnets and fields
Distinguish permanent and induced magnets and choose magnetic materials for appropriate uses.
Describe pole interactions and why cutting a magnet does not isolate one pole.
Draw bar-magnet and uniform fields, showing direction and strength through line spacing.
Describe compass field mapping and compare directional information with iron-filing patterns.
Explain compass alignment with Earth's magnetic field and evidence for a magnetic core.
Current-produced fields
Describe evidence for current-produced magnetism and circular straight-wire fields, including current and distance effects.
Use the right-hand grip rule with conventional current, including dot and cross diagrams.
Explain solenoid field addition, interior uniformity and the weaker external field.
Explain solenoid strengthening and pole reversal and plan controlled safe electromagnet comparisons.
Motor effect (Higher)
Explain the motor effect through field interaction and paired conductor-magnet forces (Higher).
Use Fleming's left-hand rule to predict force direction and effects of reversing current or field (Higher).
Explain perpendicular maximum force and zero force for parallel current and field (Higher).
Force calculations (Higher)
Calculate and rearrange magnetic force, flux density, current and perpendicular wire length with correct units (Higher).
Electric motors
Explain motor-coil turning forces using Fleming's left-hand rule (Higher).
Explain split-ring commutators and brushes in a continuous d.c. motor (Higher).
Predict motor reversal and stronger turning effects and explain energy transfers (Higher).
