I figured it out...all i needed to do was set it up as a matrix and find the determinate(ie the cross product) and everything worked out fine!

got it! Alright, the only thing that was confusing me was the units for momentum and trying to set as one variable... What i found was B = mv/rq where mv was the momentum that they gave us. After that it was just plugging in the numbers. I got my final answer to be 1.5 T

A 2.0 m long wire carries a current of 8.2 A and is immersed within a uniform magnetic field B. When this wire lies along the +x axis, a magnetic force F= (-2.2 j)N acts on the wire, and when it lies on the +y axis, the force is F = (2.2 i -4.2k)N. I saw through inspection that B in the y...

Protons with momentum 2.2×10−16 kg*m/s are magnetically steered clockwise in a circular path 1.8 km in diameter at Fermi National Accelerator Laboratory in Illinois. I am asked to find the magnitude and direction of the field in the magnets surrounding the beam pipe... I'm fairly certain...
