By way of comparison, Earth's magnetic field is created by swirling molten iron and nickel in the planet's core, resulting in a north and south pole which constitutes what's known as a dipole.
And on average we find that there's less than 1 kilogram of dark matter in a volume of that of the Earth. If you compare ... of rotational energy through magnetic dipole radiation.
Ferromagnetism is a form of magnetic ordering in which the intrinsic magnetic dipole moment ... are essential for energy conversion, but rare earth dependence and brittleness limit their use.
Seeman and Wu concluded that at least two characteristics were shared by all of the interviewees. First, each reported an ...
Electric and magnetic fields are important factors to be considered ... As shown in Figure 1, a transmission line can be designed as a dipole by using bundled conductors and energizing traditional A ...
Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...
If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...
Have you ever played with a magnet and stuck it in a sandy wash? It will pick up lots of black stuff. Some call it black sand; some might think ...
Iridium-doped iron-cobalt (Fe-Co-Ir) alloys, previously identified through machine learning, have been shown to have enhanced magnetic properties, surpassing even the widely used pure Fe-Co alloy.
