Homework Statement
Show that two measurements F_{1} and F_{2} of magnetic force at a fixed point are sufficient enough to determine B at that point as (see picture) provided v_{1} and v_{2} are orthogonal.
2. Homework Equations
F = qv x B
B_{z} = cF_{x}/(qv_{y})
B_{y} = cF_{z}/(qv_{x})
B_{x} = cF_{y}/(qv_{z})
The Attempt at a Solution
I have 3 pages of various attempts that I can upload if necessary. I can't seem to figure out what the orthogonality has anything to do with and to be honest, the professor wrote this down on the board and he could have forgotten an exponent or something like that. If someone could even just give me a hint as to what the orthogonal velocities has anything to do with, I may be able to figure it out from there.
