Homework Help: 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

    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....... :)
