1. A magnetic-field generator used in construction of a cell sheet, comprising:
a magnetic circuit assembly configured to generate a magnetic field for the construction of the cell sheet using magnetic force caused by the magnetic field; and
a power control system configured to generate and control electric power to
magnetically charge the magnetic circuit assembly using the electric power,
wherein the magnetic circuit assembly includes at least one core member and at least one magnetic or ferromagnetic table member, and a common width of each of the at least one table member is greater than a common width of each of the at least one core member; and
wherein each of the at least one core member has an outer region and an inner region, and a magnetic permeability of the outer region is different from the magnetic permeability of the inner region.
