Chapter 15

Magnetism and electromagnetism

A current produces a magnetic field and can experience a force in another magnetic field.

Keep current, field and force directions distinct, then use them to explain an observation or a turning coil.

Magnet properties and induction, compass mapping, current-produced fields, conductor forces and the turning effect on a coil. For K326 / K327 (2027) / 5086 / 5087 (2026).

  1. Magnet properties and observations

    Use attraction and repulsion to distinguish what an observation proves about a magnet or magnetic material.

  2. Induced magnetism and material choice

    Predict magnetisation near a magnet or inside a coil, then choose a material for retaining or losing it.

  3. Finding field direction with a compass

    Use the north-seeking end of a compass to plot a local field direction and follow a field line.

  4. Magnetic field patterns

    Draw consistent arrows around one bar magnet and between unlike or like facing poles.

  5. Magnetic fields from currents

    Draw straight-wire and solenoid fields, then predict the effects of changing or reversing current.

  6. Magnetic force and its direction

    Use a controlled wire experiment and Fleming's left-hand rule to determine force, field and current directions.

  7. Why a current-carrying coil turns

    Find the forces on the two active sides and explain their combined turning effect.
