Question

A cube of edge length = 2.4cm is positioned as shown in Figure P20.7. There is a uniformmagnetic field throughout the region with componentsBx = +10.0 T, By = +7.0 T, andBz = +7.0 T. (a) Calculate the flux through the shaded face of thecube.
1 T·m2
(b) What is the total flux emerging from the volume enclosed by thecube (i.e., the total flux through all six faces)?

Explanation / Answer

(a)  the flux through the shaded face of thecube =Bx*L2=10*0.0242=5.76*10-3T·m2
(b) the total flux emerging from the volume enclosed bythe cube each face of the cube always has its parallel pair => netflux of each pair will cancel each other => So total flux=0T·m2
