Abstract Using the nuclear shell model, we study the influence of ultra-strong magnetic field on the electron capture nuclei reactions 56,58Co→56,58Fe, 56,57Ni→56,57Co, 52,53Fe→52,53Mn and 57,60Cu→57,60Ni. The results show that the electron capture rates of most iron group nuclei are increased greatly in the ultrastrong magnetic field, and even exceed three orders of magnitude in the range from 5×1013 G to 2.5×1017 G.
