Power inductor has a magnetically isotropic core including two or more laminations. At least a first lamination can include anisotropic magnetic material having a first orientation of magnetic anisotropy. At least a second lamination can include anisotropic magnetic material having a second orientation of magnetic anisotropy, the second orientation being different than the first orientation.
