The right-hand rule involves holding the conductor in your right hand, aligning the thumb with the current’s direction, and letting the curled fingers indicate the magnetic field’s circular orientation.

The right-hand rule aids in determining the direction of the magnetic field around a current-carrying conductor. If the right hand is used, with the thumb pointing in the direction of the current flow, the curled fingers represent the direction of the magnetic field lines encircling the conductor. This rule is a practical application of Ampere’s Circuital Law. By aligning the thumb with the current, the rule provides a consistent method to visualize the magnetic field’s orientation. This visualization is crucial for understanding electromagnetic interactions, such as those occurring in solenoids, transformers, and other devices in electrical engineering.
