Excerpt from Technologic Papers of the Bureau of Standards, Vol. 17: 1922-1924 The Specimens were magnetized in a solenoid 50 cm (20 inches) long. The concentration of the winding was such that the nu merical value of the magnetizing force within the middle portion of the solenoid was approximately 100 times that of the current in amperes. The test coil of 1200 turns was wound on a brass form and extended over about two-thirds of the specimen. The readings of magnetic induction were taken by means of a bal listie galvanometer.
