Earth's magnetosphere is an area of charged particles surrounding the Earth in an irregular shape, with an elongated tail extending away from the sun and its solar wind. The magnetosphere occurs in response to Earth's magnetic field, which is generated by convection in its liquid iron outer co...
What is a Magnetic Field? - Lesson for Kids Magnetic Field: Definition & Creation Lesson Transcript Instructors Jim Heald View bio Elaine Chan View bio Magnetic fields are generated when charged particles move around. Explore more about magnetic fields, their source, current carrying conductors, and...
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquidironin Earth'souter core, a phenomenon called the geodynamo. Despit...
By providing the through-hole 2 in the primary conductor 1, a portion of the current I to be measured is the bypass current Ia goes around the through hole 2. Magnetic field component Hx only in the X-axis direction is generated from the current flowing through the portion having no ...
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
The magnetosphere is the area around a planet where the magnetic field created by the core is found. Earth's magnetosphere is stronger than any other magnetosphere around planets in our solar system. By shielding the planet from solar particle radiation, it helps to ensure the continued existence...
such as the Internal or the Main Field (generated by geodynamo) (Bullard1949) and the External Field (generated by interactions between the solar wind and the Earth’s ionosphere) (Glassmeier and Vogt2010). Currently, Earth’s magnetic poles are near geographical poles (Clark1979), however, ...
Twice as large as any previous generated. The advantage of this is that once the initial fusion reaction occurs, the larger plasma will generate enough energy to keep itself hot, to keep the fusion reaction going. And second, ITER will use super-conducting magnets to form the magnetic field,...
Magnets are at the heart of this. The “common mode choke”, for instance, is composed of two coils of conductor, each containing a magnet. The magnetic fields they produce “choke” the noise – the spurious electrical signals – that is generated by all this switching on and of...
