Effects of large horizontal winds on the equatorial electrojet
... The interaction between the lower thermospheric winds and the ionospheric plasma is qualitatively different at the dip equator compared to other latitudes. Winds are most prone to generate dynamo electric fields where the magnetic field lines are nearly horizontal, and the Cowling conductivity in th ...

Measurement of Gravitomagnetic and Acceleration Fields Around
... Since the measurements of WMAP (Spergel et al., 2003), we know that the universe is best described as being flat and it has a non-zero cosmological constant Λ. A well known cosmological consequence is the observed acceleration of the expansion of the universe. Under these circumstances, gravity can ...

Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.
