The invention discloses bending-cracking-preventing magnetization-free annealing electromagnetic pure iron. A microstructure of the bending-cracking-preventing magnetization-free annealing electromagnetic pure iron is isoaxial ferrite, the average grain size of the isoaxial ferrite is 60 microns to 100 microns, and the volume fraction of the isoaxial ferrite with the size larger than 60 microns exceeds 80%; and the magnetization-free annealing electromagnetic pure iron has occluded foreign substance, the occluded foreign substance is an Al2O3-MnS system, the area percentage of the Al2O3 occluded foreign substance is lower than 0.01%, and the area percentage of the MnS occluded foreign substance is lower than 0.004%. Correspondingly, the invention further discloses a manufacturing method ofthe magnetization-free annealing electromagnetic pure iron. The bending-cracking-preventing magnetization-free annealing electromagnetic pure iron has the low coercive force and the high bending-resistant characteristic, the hardness of the magnetization-free annealing electromagnetic pure iron is 90 Hv-130 Hv, the yield strength in the rolling direction is larger than or equal to 200 MPa, the strength of extension is larger than or equal to 300 MPa, and the ductility (A50) is larger than or equal to 32%.
