How does a magnetic compass needle deflect in the following situations?
i. If we Place a straight current carrying wire (the direction of the flow current is from north to south) such that the wire is placed over a compass needle such that the wire is parallel to the compass needle,
ii. If we Place a straight current carrying wire (the direction of the flow current is from south to north) such that the wire is placed below a compass needle such that the wire is parallel to the compass needle,
