Write right-hand thumb rule and right-hand rule.

Fleming’s right-hand rule: Stretch the thumb, forefinger and middle finger of the right hand so that they are mutually perpendicular to each other. If the index finger indicates the direction of the magnetic field and the thumb shows the direction of motion of conductor, then the middle finger will show the direction of induced current.

Right-hand screw rule: The direction of these circular magnetic lines is dependent upon the direction of the current.

When we stretch our thumb and all the four fingers are making a fist then the direction of circular magnetic field lines are represented by the closing direction of the fingers and the direction of stretched thumb gives the direction of the current.

The direction of the circular magnetic field lines can be given by Maxwell's right-hand grip rule or Right handed corkscrew rule.
