distortion in transformer cores, N. Partridge, 1939

This is the first of a series of articles in which the question of amplitude distortion arising in the iron core of a transformer will be dealt with on a quantitative basis. Information on this subject is scarce and the design data given is the outcome of original research by the author.

Be aware that tis articles appeared in the The Wireless World magazine from around 1939 (!). I’ve found some decent scans here: 1, 2, 3, 4.
