Answer 1

Maxwell’s Right Hand Thumb Rule:
The- direction of the magnetic field produced by a current-carrying conductor is given by Maxwell’s right hand thumb rule.



It states that if you holding the current-carrying conductor in your right hand such that the thumb points in direction of the current, then the direction in which the fingers encircle, gives the direction of magnetic lines. This rule is also called Maxwell’s Corkscrew Rule.
This rule can also be stated as if we consider ourselves driving a corkscrew in the direction of the current, then the direction in which we rotate the screw is the direction of the magnetic field.
