A current through a horizontal power line flows in west to east direction. What is the direction of magnetic field at a point directly below it and at a point directly above it ?
Answers
Answer:
Explanation: The current is in the east-west direction. Applying the right-hand thumb rule, we get that the direction of the magnetic field at a point below the wire is from north to south. The direction of the magnetic field at a point directly above the wire is from south to north.
Answer:
Direction of magnetic field is given by the right hand thumb rule, where the thumb points towards the direction of current flow and the rotation of palm gives the direction of magnetic field line.
1) At a point below the line :
If the current is flowing from east to west then the direction of magnetic field at a point below it will be towards SOUTH.
1) At a point above the line :
If the current is flowing from east to west then the direction of magnetic field at a point above it will be towards North.
