Now when current is made to pass through the niobium coil (wrapped around tantalum) it produces a magnetic field, which in turn reduces (kills) the superconductivity of the tantalum wire and hence reduces the amount of the current that can flow through the tantalum wire. Hence one can control the amount of the current that can flow in the ...
Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.
Medium close-up view, captured with a 70 mm camera, shows tethered satellite system deployment.. Electrodynamic tethers (EDTs) are long conducting wires, such as one deployed from a tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting electrical energy to kinetic energy.

The heliospheric current sheet, or interplanetary current sheet, is a surface separating regions of the heliosphere where the interplanetary magnetic field points toward and away from the Sun. [1] A small electrical current with a current density of about 10 −10 A /m 2 flows within this surface, forming a current sheet confined to this surface.
Health officials are warning of waterborne disease risks associated with splash pads and fecal matter after finding that more than 10,000 children and adults have been sickened over 25 years.
In plasma physics, a force-free magnetic field is a magnetic field in which the Lorentz force is equal to zero and the magnetic pressure greatly exceeds the plasma pressure such that non-magnetic forces can be neglected. For a force-free field, the electric current density is either zero or parallel to the magnetic field.
Spain has arrested one of its top police officers after 20 million euros were found hidden in the walls of his house, as part of a probe into the country's largest-ever cocaine bust.. Described as ...
I urge you to rewatch that video as many times as you need to (Washington fans: infinite, Bears fans: 0) to get the point here. Stevenson was actually talking trash while the play was unfolding ...
