Force on a copper loop entering into a magnetic Field B with speed v

[QUOTE="kuruman, post: 6206475, member: 192687"] It looks good except for the wire resistance. The resistance of a wire is given by ##R=\dfrac{\rho L}{\pi r^2}##, where ##L## is the length of the wire and ##r## is its radius. What are these two quantities in this case? Specifically, why is the length ##2v+w##? Does the loop perimeter get to be longer when it moves faster? Also, in the last equation for the force you forgot to square ##(\frac{d}{2}).## [/QUOTE]
