Answer 1

the forefinger, the middle finger and the thumb of the right hand are held in the three mutually perpendicular directions and if the forefinger points along the direction of the magnetic field and the thumb is along the direction of motion of the conductor, then the middle finger points in the direction of the induced current.

this rule is used for generators which generates current , the rule is helpful in finding the direction of the induced current in the generator.
