Improving a magnetic shield: what works and what does not 26 March 2013 Kiril Marinov 1 Slide 2 Cylindrical shell in an external homogeneous field A ferromagnetic cylinder in an external homogeneous field B 0 =0.1T B in max Boundary conditions If 2 / 1 >100 and B 1 ~1.5T is B 2 >150T? An interface between two magnetic materials: H || must be continuous across the interface The mu-metal has to saturate. This results in 2
