We have used high-resolution zoom-in simulations of direct collapse to supermassive black hole (SMBH) seeds within dark mater halos in the presence of magnetic fields generated during the collapse, down to 10 −5 pc or 2 au. We confirm an efficient amplification of magnetic field during collapse, the...
