WebApr 11, 2024 · The transition from two-rail arrays to monomer arrays that takes place between 0.6 and 1.4 µM Ca 2+ might, therefore, weaken the cylindrical crystal, leading to a decrease in the stretching force of the SR to partially close the calcium permeation pore of the RyR (see Figure 12). A Halbach cylinder is a magnetized cylinder composed of ferromagnetic material producing (in the idealized case) an intense magnetic field confined entirely within the cylinder, with zero field outside. The cylinders can also be magnetized such that the magnetic field is entirely outside the cylinder, with zero field inside. Several magnetization distributions are shown in the figures.
