In Oersted experiment, when the current carrying conductor is held above the magnetic needle and current is sent from south to north, between the conductor and the magnet, who will expert force on the other?
Answers
Explanation:
Oersted conducted an experiment to study the magnetic effect of electric current. In this experiment he observed the deflections of a compass needle placed in close proximity of an electric wire carrying current. He observed that in the absence of current the needle came to rest in Earths North-south direction under the influence of Earths magnetic field. However, when the needle was kept below the wire and current was passed from A to B the north pole of the needle deflected towards the west and on reversing the direction of the current from B to A, it deflected towards the east. Similarly, when the needle was kept above the wire and current was passed from A to B the north pole of the needle deflected towards the east and on reversing the direction of the current from B to A, it deflected towards the west. This indicates that the direction of the magnetic field depends on the direction of current.
Answer:
The current-carrying conductor will exert a force on the magnetic compass needle.
Explanation and Other Related Observations:
The current-carrying conductor produces a magnetic field and this magnetic field exerts its magnetic influence on the compass needle. When current flows from South to North, the North Pole of the compass needle will be deflected towards the West. Direction of deflection of compass needle would change once the direction of flow of current through the conductor changes.
