how left and right hand rule is used

Expert Answer:

Fleming’s Left-Hand Rule gives the direction of the magnetic force acting on a charged particle moving in a magnetic field, or a current carrying conductor kept in a magnetic field.
 
 
 
Fleming’s Left-Hand Rule: Stretch the thumb, forefinger and middle finger of the left hand such that they are mutually perpendicular to each other. If the forefinger points in the direction of the field and the middle finger in the direction of the current, then the thumb gives the direction of motion or the force on the conductor.
 
Fleming’s Right-Hand Rule is used to find the direction of induced current in a coil encountering a change in a magnetic flux with time.
 
Fleming’s Right-Hand Rule: Stretch the thumb, forefinger and middle finger of the right hand such that they are mutually perpendicular to each other. If the forefinger points in the direction of the field and the thumb in the direction of the motion of the conductor, then the middle finger gives the direction of induced current in the conductor.
