Electromagnetic Induction qns

  1. Jul 2, 2011 #1
    Fig.35 shows a light and flexible conducting loop X freely hung on a smooth horizontal rail. A
    bar magnet PQ approaches the loop from the right. Which one of the following descriptions
    about this process is correct?



    A If P is a N-pole, the loop will be repelled to the left and its area will increase slightly.
    B If P is a S-pole, the loop will be attracted to the right and its area will decrease slightly.
    C No matter whether P is a N-pole or a S-pole, the loop will be repelled to the left and its area
    will increase slightly.
    D No matter whether P is a N-pole or a S-pole, the loop will be repelled to the left and its area
    will decrease slightly.

    can anyone help me with this qns? i've attached the diagram alrdy. im not sure if the area will increase or decrease. and why?
