star, and galaxy. The magnetic field surrounding Earth helps to protect us from the sun's violent rays and helps to create the auroras that light up the polar regions. Now you will be able to harness that power in your own little corner of the universe by creating your ...
Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet....
To generate cooling spans, rotating permanent magnet assemblies are used to cyclically magnetize and demagnetize magnetocaloric materials, which change their temperature under the application of a magnetic field. In this work, an axial rotary permanent magnet assembly, aimed for commercialization , is ...
Magnetic Fields: Magnetic fields occur in nature and can also be generated. The SI unit of measurement that is used to describe a magnetic field is the Tesla, named after the physicist, Nikola Tesla. You can visualize magnetic field lines by dropping iron filings near a bar magnet. ...
This book is an excellent introduction to proton precession magnetometers. It starts with a simple nontechnical explanation of how these magnetometers work. The rest of the book is then devoted to a detailed description of how to build a magnetometer called the Magnum. The table of contents and...
I have a sphere of Terfenol-D in air as you know Terfenol-D is a magnetostrictive material, so when you apply a magnetic field its changes its shape. I want to model this thing in COMSOL that i want to apply a certain magnetic field and see how the shape of...
Building a 12 V Generator Alternators and generators both useelectromagnetic inductionto generate power. Generators in cars and other vehicles use a pulley connected to a drive shaft such that the pulley coils wire around in a circular direction to create a magnetic field that produces a current....
