Dear student,

Right Hand Thumb Rule:

                 If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped fingers will give the direction of magnetic field lines.

Accordingly if current in wire is vertically upward, the magnetic field lines are anticlockwise, while if current in wire is vertically downward, the magnetic field lines are clockwise.

Some of the Right Hand Thumb Rule:

  • Right Hand Palm Rule No 1:

                 If we stretch our right hand palm in such a way that the thumb points along the direction of current (I), the stretched fingers towards the observation point P, then the direction of magnetic field will be along the outward drawn perpendicular to palm.
