A superconducting bulk cube subjected to magnetization, to be simulated in 3-D.
Bulk side: 10 mm, Jc=10^8 A/m^2. In case power-law is used: n=100. The cube is subjected to a sinusoidal magnetic field in the z direction: amplitude=200 mT, frequency=50 Hz.
Compare J distributions at the cross-sections: Jy at y=5 mm, Jz at y=0.12 mm and z=1.1 mm, |J| at z=0.12 mm and z= 5 mm.
Compare also initial magnetization curve M(H) from t=0 s to the first peak (t=0.005 s).
