Excerpt from A Comparison of the Formulas for the Calculation of the Inductance of Coils and Spirals Wound With Wire of Large Cross Section
In a recent paper Doctor Snow (1) has derived a formula for the calculation of the inductance of a helical coil wound with wire of any desired cross Section, and has illustrated its use both for round wires and for wires of rectangular cross section. Snow's formula is very accurate, since no terms greater than those of the fourth power in the ratio of pitch of the winding to the radius of the winding form have been neglected. It also takes into account the helical shape of the winding, and thus allows for the effect of the axial component of the current in contributing to the magnetic field. This is true of no other existing formula, so that Snow's formula is able to serve as a standard in investigating the accuracy of other formulas for the inductance of a solenoid.

Paperback. Condizione: New. Print on Demand. This book delves into the intricate world of inductance, a fundamental concept in electrical engineering. It focuses specifically on the calculation of inductance for coils and spirals, exploring various methods and formulas developed by prominent figures in the field. The author presents a comprehensive analysis of the summation method, a technique that relies on summing the inductance of individual turns of wire in a coil, and compares it to the Rosa method, which utilizes a theoretical current sheet model to estimate inductance. Throughout the book, the author engages in a meticulous examination of the strengths and limitations of each approach, dissecting the assumptions and approximations inherent in each method. The work delves into the historical context of inductance calculation, referencing contributions by scientists like Strasser, Esau, and Koga, highlighting the ongoing development of formulas and techniques to achieve greater precision. A key theme explored is the quest for accuracy in inductance calculations, particularly for complex coil geometries like polygonal solenoids and spirals. The author meticulously analyzes the error terms introduced by different methods, ultimately advocating for the generalized Rosa method as a simple and accurate approach for a wide range of coil configurations. The book concludes by demonstrating the applicability of the Rosa method to real-world applications, showcasing its effectiveness for calculating the inductance of coils with varying cross-sections, including round and rectangular wire.
