I have a coordinate system, (x,y,z). There is a uniform-magnetic-field of 2.0 T that exists along
the direction of the y-axis. There is a rectangular plane bounded by the points
Calculate how much flux is traveling through the rectangular plane.
Flux = B (dot) A (dot) d
The Attempt at a Solution
Since the rectangular plane is not changing, the magnetic-field is just dotted with the surface. And this surface is composed of the dot product of the Area and the Direction.
I can easily find the area, but I don't know how to find the direction.
What do I do with the information that tells me the B-field exists along the y-axis?
