How to calculate the Magnetic Force of THE "Right Triangle" influenced by a Line
when the magnetic field isn't constant B=u0*I/2piR?

2. Relevant equations
B=u0*I/2piR
F=iLB

3. The attempt at a solution
I can use F=iLB to calculate the bottom line.
But how to calculate the two other sides magnetic field.
How to integral the magnetic field?
Is it possible to use the middle point of the two sides to represent the whole line?

F=∫IXB dL

Consider you can compute the integral once you figure out how to connect the two variables R and L

That would work only if the magnetic field varied linearly with distance from the wire at the bottom, e.g. B = kr. I think you need to set up an integral, as throneoo noted.
