Wraps. Etat : Good. First Edition. First Edition. [4], 99 pages. Illustrated. Printed tan covers. 8 1/4 x 10 5/8 inches. Well read worn copy with creasing and wear including minor loss to spine panel. Marked "Examination Copy with the compliments of J. W. Edwards, PUBLISHER, Ann Arbor Michigan" on the cover. Lithoprinted at Edwards Brothers Inc. Wraps. The author Alva W. Smith was in the Department of Physics at Ohio State University during an interesting period of time for electrical engineering and related disciplines. In 1948 the transistor was invented, which changed electronics forever. This is a great example of what was being taught in a University Environment at that time. The manual is organized as a laboratory experiment instructor, with a section on reports and how they should be written, followed by the 36 experiments. Good form for engineers is suggested - put your results in a permanently bound record, not loose pages. Cross out errors, don't erase them - you might need to refer to these later. The Experiments have a short Theory section, followed by the Experiment. There are thirty-six experiments including "Standardization of an Ammeter by Means of a Leeds and Northrup Potentiometer" ; "The Commutator Type of Watt-Hour Meter" ; "The Cathode Ray Oscillograph" and many other interesting topics.…

Paperback. Etat : New. Print on Demand. This book investigates the effect of a constant magnetic field on small cyclic changes in a magnetic substance. The author begins by summarizing past research on this topic and the impact of alternating current on magnetic permeability and energy losses. The book describes in detail the experimental setup and methodologies used to conduct the study. This includes the measurements taken and instruments used to determine the alternating current permeability and resistance of an iron-cored toroid. The author also outlines two methods for measuring alternating current permeability and energy loss. The author presents the experimental results in the form of graphs and tables, showing the dependence of the alternating current permeability and energy loss on the superposed constant magnetic field. The results indicate that the permeability is highly dependent on the direct current induction and passes through cycles as the iron is carried through a hysteresis cycle. The iron loss is also found to be a function of the direct current induction, reaching a minimum at a specific value of induction. The author concludes by discussing the implications of these findings for the design of polarized electromagnets and other devices that utilize magnetic materials. This book provides valuable insights into the behavior of magnetic materials under the influence of both alternating and constant magnetic fields and is a valuable resource for researchers and engineers working in this field.
