A 0.150 T magnetic field B crosses the xyplane perpendicular to the x axis and at an angle of45.0° to the y axis. A square surfacewith sides of length 7.00 m lies mainly in the xyplane, but a 1.50 m section of it at one end is bent 90°in the negative z direction. What is the total magneticflux through the surface? Choose directions for the area vectors sothat the flux through each surface is positive.
