Ahorizontal wire carries a current straight toward you. from your point of view, the magnetic field at a point directly below the wire points

a) directly away from you.
b) to the left.
c) to the right.
d) directly toward you.
e) vertically upward.

C) to the right.

Explanation:

When a horizontal wire carries a current that is coming directly towards the observer then the direction of the magnetic field just below the wire will appear to be pointing towards right side for the observer.

This can be easily predicted by using the Maxwell's right hand thumb rule where the thumb points the direction of current and the curl fingers point the direction of the magnetic field.

option (c) is correct.

Explanation:

According to the Maxwell's right hand thumb rule, the direction of current is represented by the thumb and the curling of fingers gives the direction of magnetic field.

So, the direction  of magnetic field is towards right.

the correct choice is a .
