As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

Multiferroic materials, in which electric and magnetic properties are combined in promising ways, will be the heart of new ...

During solar minimum, the sun's magnetic field is close to a dipole, with one north pole and one south pole, similar to Earth's magnetic field. But as we shift toward solar maximum, "the sun's ...

As MPI transitions toward clinical use, several challenges remain to be addressed, including tracer design, image reconstruction algorithms, and optimized field configurations, to achieve improved ...

Abstract: The pulsed electromagnetic radiation from a vertical magnetic dipole above a conducting Earth is investigated theoretically. The modified Cagniard method is used to derive closed form ...

Multiferroic materials, in which electric and magnetic properties are combined in promising ways, will be the heart of new ...

A magnetic field has the ability to induce a current in a conductive object – for transmission ... As shown in Figure 1, a transmission line can be designed as a dipole by using bundled conductors and ...

NASA's MMS mission discovered whistler-mode chorus waves in an unexpected region, the terrestrial mid-tail neutral sheet, ...
