A horizontal wire carries a current straight lows of view, the magnetic field caused by this current points directly away from you. points to the left. circles the wire in a clockwise direction, circles the wire in a counter-clockwise direction

Solution

Using the ampere’s right hand thumb rule, when a thumb indicates the current direction then the curl of the remaining fingers indicates the magnetic field direction.

Here, the current carrying in the straight wire towards the person. Hence, the keep the right hand thumb in this direction, then the curl of the fingers is in the counter-clockwise direction. Therefore, the magnetic field cause by the current along in the counter-clockwise direction.

So, the correct option is (d).
