Solution

The correct option is A Maxwell's right hand thumb rule
The rule that helps in finding the direction of magnetic field produced by current carrying conductor is Maxwell's Right Hand Thumb Rule. It states that if one holds the wire carrying current in the right hand so that the thumb points along the wire in the direction of the current, then the fingers will encircle the wire in the direction of the lines of magnetic force.
