उत्तर
The right-hand thumb rule determines the direction of a magnetic field around a current carrying wire. It states that if we hold the current carrying conductor in the right hand such that the thumb points in the direction of the flow of current, then the fingers encircle the wire in the direction of the magnetic field lines.
