Explanation:
Right hand thumb rule : Point the thumb of your right hand in the direction of the current flow, the direction of curvature of the fingers will give us the direction of the magnetic field produced by current carrying wire. This rule was given by Maxwell.
1) If the current is moving in upward direction , the direction of the magnetic field will be in anti clock wise direction.
2) If the current is moving in downward direction , the direction of the magnetic field will be in clock wise direction.
We know that -
Where,
First we convert height into meters.
1 km = 1000 meters
3 km = 1000 * 3 meters = 3000 meters
So, putting the values in the above formula, and by taking 'g' = 9.8 m/s², we get-
