Exam points

  • use the right-hand rule to decide whether the field at a point is into or out of the page around a wire
  • explain stronger or weaker net B on either side of a current-carrying wire by adding or opposing fields
  • interpret magnet or coil setups to choose the field pattern, uniform region or direction giving maximum deflection
