Sunspots and magnetic and electric disturbances
Sunspots are regions of high physical and magnetic turbulence on the Sun. They increase and The relationship between electricity and magnetism is intimate. The Disturbance storm time (Dst) index is used to identify more than Early works that investigated the relation between .. We are simulating materials for converting waste heat energy into useable electrical energy. Abstract. We have studied the relationship between three different versions of the sunspot number. (Group, International and American sunspot number) and the.
Explain the relationship between sunspot number and electrical disturbances on Earth?
In the number of spots on the Sun was near the peak of a relatively low sunspot cycle and the article quotes a number of eminent astronomers disagreeing on whether solar activity was increasing or decreasing. For the record looking at a graph of sunspot numbers indicates a peak in It then says, Whether the solar activity is the cause of the earthquakes, volcanic eruptions, cyclones, tornadoes, and the disturbances that follow in their train is a problem yet unsolved.
That sunspots are due to magnetic fields was discovered by American astronomer George Ellery Hale 24 years after the Scientific American article. In Hale, observing with the newly-built foot metre solar tower, used a special prism to examine the polarisation of the light from sunspots.
With a spectroscope the light can be broken up into its component colours and specific wavelengths or lines due to ions of particular elements can be seen. In previous work Hale knew that some of these lines are in fact close doublets, that is, instead of one spectral line due to an ion there are two that are very close in wavelength.
What is the relationship between sunspots and electrical disturbances
On 24 and 25 June he found that these doublets are polarised, that is, the radiation from the ions vibrate in specific directions. Furthermore the two components of the doublets had opposite polarisations.
Hale saidPhotographs like these seemed to leave no doubt that the components of the spot doublets are circularly polarised in opposite directions. Since the only known means of transforming a single line into such a doublet is a strong magnetic field, it appeared probable that a sunspot contains such a field, and that the widening and doubling of the lines in the spot spectrum result from this cause.
Sunspots and magnetic fields – when did scientists discover the connection? – Observations
Thanks to George Ellery Hale and his successors we know far more about the Sun and its spots than scientists did back in May when the Scientific American article was written. What is the relationship between magnetism and electricity? The movement of charge carriers free electrons, in the case of metal conductors is accompanied by a magnetic field.
In other words, an electric current is accompanied by a… magnetic field, whose 'shape' can be described as concentric cylinders surrounding the direction in which the current is flowing. The main reason for both being related is: A flowing current can produce a magnetic fieldand an electric current can be induced using magnetic field Share to: What is the relationship between electricity magnetism?

For gravity they are gravitons and for the electromagnetic force they are photons light or electromagnetic waves. Photons include everything from radio waves through microwaves, infra red, visible light to gamma rays.
