Vedclass · Answer

(C) $1$. The loop is in the north-south vertical plane. The current at the top is towards the south.$2$. By applying the Right-Hand Thumb Rule,if you curl your fingers in the direction of the current (clockwise when viewed from the east),your thumb points towards the east.$3$. Specifically,at the center and along the axis,the magnetic field lines emerge from the face where the current appears to flow counter-clockwise and enter the face where it appears clockwise.$4$. Viewed from the east,the current flows clockwise. Thus,the magnetic field lines point towards the east at point $A$ (east of the loop).$5$. Viewed from the west,the current flows counter-clockwise. Thus,the magnetic field lines point towards the east at point $B$ (west of the loop).$6$. Therefore,the magnetic field is towards the east at both points $A$ and $B$.
