Answer:
- The right hand thumb rule was given by Maxwell
- Right hand thumb rule is used to find out the direction of the induced current or the direction of the magnetic field
- The right hand thumb rule states that if we hold a straight current carrying conductor with our right hand such that the thumb points in the direction of the current, then the curled fingers indicate the direction of the magnetic field lines
- If the current is flowing in the downward direction, then the direction of the curled fingers will be in a clockwise direction, and if the current is flowing in the upward direction, then the direction of the curled fingers will be in an anticlockwise direction
- This rule is very useful as we can use it to find the direction of the current induced while we are knowing the direction of the magnetic field or we can use it to find the direction of the magnetic field while we are knowing the direction of the current
