1. Electric current flowing through a conductor produces a magnetic field.
2. The field so produced exerts a force on a magnet placed in the vicinity of the conductor.
3. The magnet must also exert an equal and opposite force on the current carrying conductor.
4. The direction of the force depends on the direction of the current and the direction of magnetic field.
5. The displacement of the rod is maximum, when the direction of the current is at right angles to the direction of magnetic field.
