description: A magnetic balance for the measurement of the saturation magnetization of alloys has been designed and built. The magnet develops a field strength of 21,000 oersteds in a gap approximately seven-eighths inch long and two inches in diameter, when consuming a power of 4.5 kilowatts. This field is sufficient to saturate solid metal samples of random shape. Specially shaped pole caps are used which produce a gradient in the direction of the axis of the gap which is constant to within two percent, within a volume cube three-sixteenths of an inch on edge. The ratio of saturation magnetizations of iron and nickel at room temperature agree closely with the accepted values. A new magnetic phase has been discovered in the manganese carbon system. It has been identified as ferromagnetic, but its composition and crystal structure remain unknown.

note: A MAGNETIC BALANCE AND ITS APPLICATION TO THE INVESTIGATION OF FERROMAGNETISM IN MANGANESE CARBON ALLOYS by RICHARD MOWAT SHIER A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE in the Departments of Physics and Metallurgy We accept this thesis as conforming to the standard required from candidates for the degree of MASTER OF APPLIED SCIENCE. Members of the Departments of Physics and Metallurgy THE UNIVERSITY OF BRITISH COLUMBIA OCTOBER, 1953 ABSTRACT. A magnetic balance for the measurement of the saturation magn-etization of alloys has been designed and built. The magnet develops a f i e l d strength of 21,000 oersteds i n a gap approximately seven-eighths inch long and two inches i n diameter, when consuming a power of 4«5 kilowatts. This f i e l d i s sufficient to saturate solid metal samples of random shape. Specially shaped pole caps are used which produce a gradient in the direction of the axis of the gap which i s constant to within two percent, within a volume cube three-sixteenths of an inch on edge. The ratio of saturation magnetizations of iron and nickel at room temperature agree closely with the accepted values, A new magnetic phase has been discovered in the manganese carbon system. It has been identified as ferromagnetic, but i t s composit-ion and crystal structure remain unknown. ACKNOWLEDGEMENT The. author, i s grateful to Mr, F.K. Bowers for many helpful suggestions contributing to a much more economical magnet design than had at f i r s t been thought possible. The Steel Company of Canada, Ltd., Hamilton, Ontario, very kindly contributed 1200 pounds of iron prepaid, for the magnet yoke. The author is also grateful to Mr, R. Richter for machine work done on the pole pieces and the suspension of the magnet. The design and construction of the magnet, up to but not includ-ing the design of the suspension and the shaping of the pole caps, was done in conjunction with Mr, CV, Kidson, Funds for the…
