Answer:
(a)
Ampere's Right-Hand Thumb Rule If current is passing through a conductor in the
direction of thumb of the right hand, then the direction of magnetic field is
given by that of curvature of fingers. (1)
(b) Fleming's Left-Hand Rule If the forefinger, centre finger and thumb
of left hand are stretched mutually perpendicular and forefinger points in the
direction of magnetic field, centre finger points in the direction of flow of
electric current, then thumb points in the direction of force acting on the
conductor
(1)
(c) Fleming's Right-Hand Rule If the
forefinger, centre finger and thumb of right hand are stretched mutually
perpendicular and forefinger points in direction of magnetic field, thumb points
in the direction of motion of conductor, then centre finger points in the
direction of induced current. (1)
