The easiest way to create a powerful magnetic field is by creating a powerful electromagnet. Electromagnets are used for everything from powering tiny electronic switches (called relays) to lifting huge pieces of scrap metal. The density of the winding, the amount of current flowing through the m...

How To Build A Magnetic CoilTechnology ElectronicsHow To Build A Magnetic CoilBy Isaiah David Updated Mar 24, 2022 Piotr Wytrazek/iStock/GettyImages Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, ...
Hi there. I would like to create a uniform magnetic field in a 3D box region of space that varies with time.With the Maxwell Magnetostatic solver, I can use a combination of 'Tangential H-Field' and 'Zero Tangential H-Field' boundaries to create a unifor
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...
How to create a magnetic field without electricity. How do we know Earth has a magnetic field? How can a magnetic field be produced around a wire? How does the outer core produce the Earth's magnetic field? How do you make an iron bar magnetic?

like a bar magnet), an outsidemagnetic fieldwill tilt the axis of spin and cause it to precess like a spinning top that’s been pushed off the vertical. Changes in the outside field’s strength or direction can be detected using a probe laser to repeatedly measure the vapor’s average ...
which made the needle behave like a magnet. You had to rub in one direction to get the atoms to all line up in the same manner. If you had rubbed back and forth, the atoms would not have lined up as well, and the magnetic field would probably not be as strong, if one was create...
