Homework Statement
The rod is moving on a second rod with speed of v in the magnetic field perpendicular to rod. I know its resistance per meter. I am expected to omit megnetic field created by the current and resistance at the point where rods touch each other and calculate current. I presented the situation with drawing ( the same as in task). My calculations occured to be wrong. Why?

Check the area of the triangle as a function of time. Also, try using LaTeX for writing your equations instead of posting photos some of which are sideways.

In moving media such as your rod it's generally best to use the Blv rule rather than Faraday, although in this case it's OK to do so.
