Question

two parallel straight conductors carry the same current. what is the magnitude of magnetic field at a point 'x' which is equidistant from the conductors. give justification.

only those who answer plzzzzzzz

Answer 1

The net magnetic field at point x will be zero.

The magnetic field at a point due to a current carrying conductor is given by the right hand thumb rule.

Given the conductor carry same current in same direction,

At point x the magnetic field due to conductor A will be in upward direction following the right hand thumb rule.

Similarly at point x the magnetic field due to conductor B will be in downward direction .

Since the distance of x from both the conductors is same, hence the magnitude is also same, but the direction of both will be opposite,

Hence the both magnetic field will cancel each other.

So the net magnetic field at point x will be zero.
