Motional emf

  1. Sep 2, 2010 #1
    1. The problem statement, all variables and given/known data

    attached

    2. Relevant equations



    3. The attempt at a solution
    I=BLv/R=.0043A which is obviously wrong, not sure why though?

    parta=4.274A
    partb=clockwise
    partc=0A
    partd=no direction
    parte=4.273A
    partf=anti-clockwise.....
    you didn't convert cm unit into meter......hope this was helpful.......

    if thats right than I must just have a wrong exponent somewhere

    mind telling me how you got that because I checked mine and I keep getting 0.00427A??

    yupe....you correct....its 0.0427....sorry for previous answer and inconvinience......so wats the problem now....you getting the answer.....

    No,thats not the answer, I tried that but it tells me its incorrect.

    here the resistance 3.5ohm is of the whole loop.But,we have to consider resistance of only the length of the side which we are considering in calculation...
    R=(3.5*8)/40.
    now do calculation and hope you will get the answer....... :)
