Abstract (en)

A magnetic core (1) for electrical induction apparatus, e.g. a power transformer or a distribution transformer, comprises spaced apart yokes (5, 9) each formed of wound magnetic strip material (10), e.g. amorphous magnetic material, and legs (2-4) interconnecting the yokes (5, 9). The legs (2-4) are formed of at least substantially planar layers of magnetic material and are interleaved at their ends with the wound yoke layers of magnetic strip material (10).
