Answer #1

As the magnetic force on any moving charge of value q moving with velocity in a magnetic field of value is given as

hence if we point middle finger of our left hand in direction of magnetic field and index finger in direction of motion of positive charge or in opposite direction of motion of negative charge then direction of thumb indicates the direction of force on the charge given that thumb and fingers are mutually perpendicular to each other.

Similarly for Right hand rule if index finger points in the diection of magnetic field and the thumb points the direction of motion of a conductor in that magnetic field then the middle finger points in the direction of current induced in that conductor.
