Answer 1

The magnetic field at a point on the +x-axis near a wire carrying current in the +y-direction is directed into the page, as indicated by the right-hand rule.

Step-by-step explanation:

The direction of the magnetic field created by a current-carrying wire can be determined using the right-hand rule. For a wire carrying current in the positive y-direction (upwards), and when trying to find the magnetic field at a point along the positive x-axis, you would point the thumb of your right hand in the direction of the current (upwards), then wrap the fingers of your hand around the wire in the direction of the magnetic field lines.

At a point on the positive x-axis, the fingers of your right hand would point directly into the page. Therefore, the correct answer to the question is c. into the page.
