The ENA imager provides indirect remote sensing of the ring current ions, and the Lyman alpha detector gives a measure of the neutral hydrogen cloud about the Earth, known as the geocorona.

This aromaticity is evidenced by the chemical shift of the ring protons in proton NMR spectroscopy ( between 7.27 and 8.77 ppm ), clearly indicating a strong diamagnetic ring current.

Further, among his major scientific contributions is study of anti-aromaticity in metal clusters using ab initio molecular dynamics ( AIMD ) study of structure, electron localisation function and magnetic ring currents.

Reducing the compound at low temperatures allowed analysis of the dianion by proton NMR with the inner protons resonating at-4.5 ppm relative to TMS, evidence of an aromatic diamagnetic ring current.

The configuration of the magnetodisk's field is maintained by the azimuthal ring current ( not an analog of Earth's ring current ), which flows with rotation through the equatorial plasma sheet.

Other studies do not support the role of ?-aromaticity in cyclopropane and the existence of an induced ring current; such studies provide an alternative explanation for the energetic stabilization and abnormal magnetic behaviour of cyclopropane.
38.
For example, if the first oxidation is followed by a chemical reaction, an EC mechanism, to form a product that can not be reduced at the ring then the magnitude of the ring current would be reduced.
39.
The ring current around Earth produces a magnetic field that is directly opposite Earth's magnetic field, i . e . if the difference between solar electrons and protons gets higher, then Earth's magnetic field becomes weaker.

The source of the magnetic disturbances observed at the Earth's surface during geomagnetic storms is the ring current, whereas the sources of magnetic disturbances observed on the ground during substorms are electric currents in the ionosphere at high latitudes.
