Solution

The correct option is D West
The current carrying wire is shown in the figure.


Applying formula of magnetic force on current carrying wire,

F=i(L×B)

By using the right-hand thumb rule, we get the direction of F towards west.

Hence, option (D) is correct.
Why this question ?
Tip: The direction of current in wire is taken as reference for deciding the direction of L. Thus, L is in direction of current in wire.
