Solve the following problem with MATLAB. Plot whatever is necessary. Show the program you made to graph and solve the problem. Magnetic ball. A spherical shell of radius R, carries a surface uniform charge o and rotates with an angular velocity w. We wish to find the vector magnetic potential at an arbitrary point r in space. For this, we first rotate our reference system such that the position r is on the z axis and that the angular velocity w is in the xz plane as seen in the image. w Y ' Figure 1: Rotating spherical shell with surface charge density o.
