Claims

[Scope of utility model registration request]

An electromagnetic device is formed by stacking flat magnetic plates and has a bent part, wherein the magnetic plates of each layer are provided with tapered gaps that open from the protruding corner side to the large corner side at the target part, and these gaps An electromagnetic device characterized in that each layer is arranged alternately in an arcuate direction centering on the protruding corner.
