I was wondering what would happen if you have a current carrying wire that makes an angle with the magnetic field and how to describe its motion. Prepare yourself for the bad drawing.
I will first show how the method I used works for a simpler case where Magnetic field and current are perpendicular: https://i.imgur.com/c8HYxzt.png
Assume a charge ##Q## it will experience magnetic force to the right which will give it a speed ##V## to the right (as the whole wire moves). This creates another magnetic force pointing downward which is the reason for the back emf, This also conserves energy.
Now for this case: https://i.imgur.com/hWsaJAI.png
There will be a force ##F_{m1} ## into the page and a velocity ##V_1## into the page will result from it which will create the force ##F_{m2} ## as in the picture That will have a component in the x and y direction, I will ignore the x direction assuming we can keep a steady current, This will create a velocity ##v_2## in the x direction which finally creates ##F_{m3}## out of the page, Now this conserves energy too and it shows that the wire will move in x direction and into the page. You can link the movement in those directions together to get a function of distance
Is this approach correct? Any simpler ways?
