Electromagnetic forces written questions
Answer H2 Physics questions on magnetic fields, forces on currents and charges, and crossed-field motion, with marking guidance for signs and directions.
Learning goals
- Calculate and represent magnetic fields produced by currents.
- Sketch magnetic field lines due to currents in a long straight wire, a flat circular coil and a long solenoid.
- Analyse forces on current-carrying conductors in magnetic fields, including current balances.
- Analyse forces and paths of moving charges in uniform fields.
- Apply crossed electric and magnetic fields to velocity selection.
