**describe the interaction forces between a magnet and a current-carrying conductor to include ideas about magnetic fields **
**show that Fleming’s left-hand rule represents the relative orientations of the force, the conductor and the magnetic field **
**select and apply the equation that links the force (F) on a conductor to the strength of the field (B), the size of the current (I) and the length of conductor (l) to calculate the forces involved:
force (N) = magnetic flux density (T) × current (A) × length of conductor (m)**
explain how the force on a conductor in a magnetic field is used to cause rotation in the rectangular coil of a simple electric motor
