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 direction is 0, but I'm having difficulties with the x and z direction.
I know the equation in F=ILBsin(theta) and that i might need to use a dot product, but I'm stuck after that...
