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....... :)
