Question

When a current carrying wire is held parallel to and above a compass needle and the current flows from North to South, which direction the N-Pole of the compass needle will get deflected?
Give brief and proper answer

Answer 1

The compass needle will show the deflection in the east-west direction. This can be proved with the help of right-hand thumb rule.

• As the current flows from North to South direction, therefore using right-hand thumb rule we can find the direction of the magnetic field.

• The direction of the magnetic field at a point below the wire is from west to east. The direction of the magnetic field at a point directly above the wire is from east to west.

• Thus, the compass needle show deflection in the east-west direction.

Answer 2

Answer:

east

Explanation:

here if the current would flow from north to south direction then the force on the needle will be acting towards the east by using right-hand thumb rule .
