Solution

## The correct option is A In the positive x direction Direct your thumb towards the direction of current in the straight wire. The curl of the fingers gives the direction of magnetic field. If you point your thumb in the positive x-direction and place your fingers at y-axis, the fingers direct towards negative z-direction. Hence, the direction of the magnetic field is along the negative z-direction.
