Claim:
1. Method of forming a magnetic core, comprising: providing a powder of ferromagnetic material; pressing of a ferromagnetic material filled into a die for producing a pressed blank, the pressed blank comprising: a crossbar having a length dimension and a width dimension, wherein a ratio of length dimension to width dimension is greater than 1, at least one core leg which extends laterally of the crossbar, away therefrom, along an extension direction, and an alignment recess, and wherein the die has a structure which produces the alignment recess; sintering the pressed blank for forming a sintered core body; aligning the sintered core body relative to a second core body by means of an alignment device having an engagement element that is engaged with the alignment recess of the sintered core body prior to the alignment, wherein the alignment is carried out along directions along the length and width dimensions; and subsequently connecting the sintered core body to the second core body to form the magnetic core.
