Correct Answer: Maxwell’s corkscrew rule


Solution : The correct answer is Maxwell's corkscrew rule.

With a straight current-carrying conductor, the direction of the magnetic field is determined by Maxwell's right-hand thumb rule. The rest of the curled fingers on the right hand determine the direction of the magnetic field surrounding it if the thumb of the hand represents the direction of the current flow. Maxwell's corkscrew rule is another name for the Right-Hand Thumb rule.
