Solenoids, Electromagnets and Electromagnetic Windings

Creating an electromagnet is quite easy, as Faraday discovered, but creating one that generates a field of needed intensity, drawing minimal amperage at available voltage without over-heating isn’t so simple. Few people know how it is done, but this book shows the secrets of creating working electromagnets. It is a practical book; the maths, the charts and the information are all just right. Since 1921 better insulation and higher-permeability iron have become available, but Amps and Oersteds are the same. 342 page well illustrated paperback.

Here you'll learn the secrets of creating an electromagnet that generates a field of needed intensity, drawing minimal amperage at available voltage without overheating.

Chapters include: magnetism and permanent magnets, electric circuits, electromagnetic calculations, the solenoid, practical solenoids, ironclad solenoid, plunger electromagnets, electromagnets with external armatures, electromagnetic phenomena, alternating currents, AC electromagnets, quick-acting electromagnets and methods of reducing sparking, materials and bobbins, insulation of coils, magnet wire, insulated wire, windings, forms of windings, heating of windings, and tables and charts. There are also 233 illustrations listed showing everything from a practical multiple-coil winding to rim solenoids telescoped to form disk solenoids.

Some things have changed since 1921 such as better insulation and higher-permeability iron, but amps are still and amps and Oersteds are still Oersteds.
