Magnets

"Magnets" is a comprehensive technical treatise on the practical and theoretical aspects of electromagnetism and magnetic phenomena. Written by renowned electrical engineer Charles R. Underhill, this work serves as an authoritative guide for students and professionals seeking a deeper understanding of the design and application of various magnetic devices. The text covers a broad range of topics, including the laws of the magnetic circuit, the properties of permanent and electromagnets, and the intricate mechanics of solenoids and winding calculations.

Underhill provides detailed explanations of magnetic induction, flux, and the characteristics of magnetic materials available in the early 20th century. Through clear diagrams and mathematical formulations, the author bridges the gap between abstract physical principles and their practical realization in electrical machinery and apparatus. "Magnets" remains a significant historical reference in the field of electrical engineering, capturing the foundational knowledge that fueled the rapid development of electromagnetic technology. Readers will find a wealth of information regarding the construction of coils and the analysis of magnetic pull, making it an essential resource for those interested in the history of science and the evolution of electrical design.
