Current is passed from South to North through a conductor placed below

1.	Current is passed from South to North through a conductor placed below a freely pivoted magnetic needle.a. To which direction will the North Pole of the magnetic needle turn? b. Which is the rule used to arrive at this inference?c. State the rule.d. If the current flows in the conductor in the East West direction, what do you guess about the deflection of the magnetic needle? Explain
Answer» a. Towards east b. Ampere’s swimming rule c. Ampere’s swimming rule Suppose a man swims in the direction j of current flow in a conductor by looking towards a magnetic needle, the north pole deflects towards the direction of the left hand. d. A freely suspended magnetic needle remains in the north south direction. When the current flows in the east west direction, the magnetic field produced will be in the north south direction. Magnetic needle does not deflect.
