Question

A current through a horizontal power line flows in east to west direction. What is the direction of magnetic

field at a point directly below it and at a point directly above it ?​

Answer 1

Answer:

The direction of magnet will be west to east.

Answer 2

Answer:

See Below ↓ [( THE DIRECTION OF YOUR ANSWER DEPENDS UPON YOUR PERSPECTIVE AND THE DIRECTION FROM WHERE U R LOOKING , BUT THE MAGNETIC FIELD MOVES IN THE SAME DIRECTION , { WHICH WHEN SEEN FROM DIFFERENT DIRECTION GIVES DIFFERENT ANSWER WITH RESPECT TO ITS POSITION })]

Explanation:

If we take the horizontal power line I front of us , so that our left denotes the east and the right denotes the west , then the current is flowing from left to right . Now , if we use the right hand rule , by holding ( pls don't really hold it or be safe while doing it ) it in such a way that our thumb finger points in the direction of the flow of the current , and now if we make a fist with that hand only, keeping the thumb the same, the direction in which our rest of our finger curls , is the direction of the magnetic field which is rounding around the horizontal line. Now , the magnetic field directly above the line moves towards right side of the line ( north ) and directly BELOW the line , to left side ( south ) [ if we see it in such a way that the line stays in its own position , but we r changing our position of our eye sight from the top of the line to its bottom , the result remains the same with left and right and also with the north and south ofcourse.]

The Answer remains the same even if we are changing the east and west from left and right to right and left until and unless we r judging these whole thing by looking in the direction of the path of the current , which is right side in the first case of the explanation. by changing our perspective , the direction too changes along with north and south .

For any mistake pls pardon !

Hope it helped !!

Thanks !!!
