Adjecent figure shows a point P near a long conductor XY carrying a current I. MN is a short current carrying conductor, kept at the point P, parallel to the conductor XY.
(i) What is the direction of magnetic flux density ‘B’ at the point P due to the current flowing through XY?
(ii) What is the direction of the force experienced by the conductor MN due to the current flowing through XY?
(i) Direction of the magnetic flux density is perpendicular to the surface and inwardly directed to the plane of the paper.
(ii) Direction of force experienced by the conductor MN is towards conductor XY.
