This authoritative compilation of formulas and tables simplifies the design of inductors for electrical engineers. It features a single simple formula for virtually every type of inductor, together with tables from which essential numerical factors may be interpolated. Although compiled in the 1940s, before calculators and computers, this book provides fundamental equations that professionals and practitioners can use to produce algorithms for computer programs and spreadsheets.Starting with a survey of general principles, it explains circuits with straight filaments; parallel elements of equal length; mutual inductance of unequal parallel filaments and filaments inclined at an angle to each other; and inductance of single-layer coils on rectangular winding forms. Additional topics include the mutual inductance of coaxial circular filaments and of coaxial circular coils; self-inductance of circular coils of rectangular cross section; mutual inductance of solenoid and a coaxial circular filament and coaxial single-layer coils; single-layer coils on cylindrical winding forms; and special types of single-layer coil. An esteemed reference, this volume belongs in the library of every electrical engineer.

An Amazing Addition to My Counter!
Color: Black
At first I did not think I needed this, but after using it for almost a year, I have found out how amazing this product is. It makes the coffee I get much better and lets me pack the grind much more evenly. It is also made of entirely metal, which adds a lot of weight and makes it feel super premium. After using it almost every day for a year now, I still have not needed to replace the needles, yet it came with nine more. All of that value for such a small price makes this great for me and anyone looking to improve their coffee making.

Great little tool
I recently purchased this product after upgrading my grinder. So far it had worked well and the little magnetic holder attaches perfectly to the Breville Barista Express I have. I love that it’s magnetic and keeps the tool out of the way and in a secure spot. Additionally, they throw in a double sided 3M sticky pad for those who do not have a surface where it can magnetize to. Overall great WDT with a great storage solution.

Best WDT Tool Every Espresso Lover Needs
This tool is so easy to use. It comes with a handy holder you can stick on the side of your machine and even replacement needles for the tool itself. I’ve had the tool for over a year now have not had to replace any of the needles! The 3M adhesive on the back of the holder is amazing quality. It won’t come off your machine. The tool itself helps take out the guesswork with your espresso shot, making sure the grounds are evenly distributed before you tamp.
