Since a compass needle is a freely pivoted magnet, a current carrying wire exerts a mechanical force on the magnet. According to Newton's 3 rd law of motion if a current carrying wire exerts a force on a magnet, then the magnet will exert an equal and opposite force. Faraday discovered that when a current carrying conductor is placed in a magnetic field, a mechanical force is exerted.on the conductor which make the conductor move.
The direction of force acting on a current carrying wire placed in a magnetic field is perpendicular to the direction of current and perpendicular to the direction of magnetic field. The current, the magnetic field and the force, are at right angles to one another.
The rule is known as Fleming's Left-Hand Rule and can be stated as Hold the forefinger, the centre finger and the thumb of your left hand at right angles to one another. Adjust your hand in such a way that the forefinger points in the direction of magnetic field and the centre finger points in the directtion of current, then the direction in which thumb points, gives the direction of force acting on the conductor.
