Benchmark #4

A superconducting bulk cylinder subjected to magnetization. With the use of an axis-symmetric model the geometry can be reduced to 2-D Cylinder’s radius: R=12.5 mm Cylinder’s height: L=10 mm Jc=3·10^8 A/m^2, [t1,t2,t3]=[ 5,10,15] s, magnetic field ramp: as displayed at the bottom of the figure below (Bmax=1 T).

Compare J distributions and magnetization at t1, t2, t3; Bz profiles 2 mm above surface, dissipation.
