Problem
A student wants to predict the motion of a current-carrying conductor using Fleming’s Left Hand Rule. She holds her left hand so that her forefinger points along the current and her middle finger points along the magnetic field before reading the thumb. Which statement correctly identifies her mistake?
(a) She should point her thumb along the magnetic field and then read the motion from the fingers.
(b) She must curl her fingers in the direction of the magnetic field rather than hold them at right angles.
(c) She has interchanged the roles of the forefinger and middle finger.
(d) She should be using her right hand; the left-hand rule is only for generators.
