A silicon steel core for transformers or choke coils includes at least one silicon steel sheet core which has at least two sets of silicon steel sheets that have respectively a magnetic flux section of a different length such that when two sets of the silicon steel sheet cores are coupled, the magnetic flux sections form at least two gaps of different intervals. Thereby the silicone steel sheet sets of a smaller gap can provide adequate electric induction for the transformers or choke coils while the silicone steel sheet sets of a greater gap can reduce the saturated condition when the transformers or choke coils are in the high load condition.
