Final answer:
The statement that using the right-hand rule, when the thumb points in the direction of the current, the fingers will curl in the direction of the magnetic field is true.
Step-by-step explanation:
According to Right Hand Rule 2 (RHR-2), you point the thumb of the right hand in the direction of the current, and your fingers will naturally curl in the direction of the magnetic field loops around the wire. This is observed with compasses placed around a wire, where the needles align tangent to circular loops centered on the wire, indicating the magnetic field's direction. In more detail, if the current is flowing through a straight wire, the magnetic field created by this current will form circular loops around the wire. By employing RHR-2, your thumb indicates the direction of the current, while the curled fingers show the direction in which the magnetic field is oriented. These circular loops indicate the presence of a magnetic field and its orientation relative to the current-carrying conductor.
