A steel rod of 0.10kg rests on two metal rails inclined at an angle of 30 degrees. There is a magnetic field of 0.50T on the incline and a current of 70A flowing across the bar. Find the acceleration of the bar.
The bar is 0.12m wide**
The attempt at a solution
What I have so far is a diagram of the problem, but I'm not sure if that is correct.
My intuition is that you'd need to make an fbd of all the forces. On my fbd I have:
Fn, Fg and Fb (force due to the magnetic field). I know only a portion of the 0.50T interacts
with the rod. I'm just confused where I put the Fb in my sum of forces statements. I have two,
Fnet (paralell) and Fnet(perpendicular) [to the motion]. Thanks!
