Question

explain Right Hand Thumb Rule and their consequences

Answer 1

If a current carrying conductor is imagined to be held in right hand such that thumb points in direction of current,then curled fingers of hand indicate the direction of magnetic field.

If current flows in upward direction then direction will be anticlockwise.

If current flows in downward direction then direction will be clockwise.

Answer 2

Right hand thumb rule was given by Maxwell. So this rule is also known as Maxwell’s right hand thumb rule. According to this rule, imagine that you are holding a current carrying wire in your right hand so that the thumb points in the direction of the current, then the direction in which the fingers wrap the wire will represent the direction of magnetic lines of force.
