Hale's law (original) (raw)
In solar physics, Hale's law, also known as Hale's polarity law or the Hale–Nicholson law, describes the tendency for bipolar active regions within the same northern or southern heliographic hemisphere to have the same leading magnetic polarity with respect to the solar rotation, and for those in the opposite hemisphere to have the opposite leading polarity. It further describes how this pattern reverses from one sunspot cycle to the next. It is named after George Ellery Hale and Seth Barnes Nicholson. Hale's law, along with Joy's law, provides observational evidence for the solar dynamo.

(en) Закон Хейла, закон полярности Хейла, закон Хейла-Николсона описывает тенденцию биполярных активных областей в одном полушарии обладать одной полярностью лидирующего пятна, в другом же полушарии полярность лидирующего пятна противоположна. Также закон описывает, каким образом меняется закономерность распределения полярности от одного цикла активности к другому. Закон Хейла наряду с законом Джоя предоставляет доказательства существования солнечного динамо. (ru) |

| dbp:footer | Photospheric magnetograms taken during solar cycles 24 and 25 demonstrate Hale's law. Here, white patches indicate magnetic field lines pointing out of the page, and bipolar active regions appear as pairs of these black and white patches. In these magnetograms, the leading polarity of a given active region is the rightmost polarity. (en) |
