The Solar Wind Since our sun formed, around 4.6 one million million million years ago it has been the ultimate source of energy and light on priming. make of 73% hydrogen, 25% helium and around 50 another(prenominal) trace elements and radiating 4 x 1026 watts of energy apiece second , it has not only emitted electro magnetized radiation by the nuclear fusion of atoms in its core but overly produces huge amounts of ionised boast due to the high temperatures. This shove along is known as the solar wind and one billion tonnes is emitted each second. It is comprised of a hot plasma of free electrons and positive ions, atoms which have lost their electrons in the violent collisions at 1,000,000°K. innovation a plasma, it can conduct electric currents and its particles, with the entrained solar magnetized business line, can be steered by other magnetized fields. It is ejected forever from the suns corona, but sometimes more violent solar action at law occurs, solar fl ares and prominences, and sends out broad amounts at one time. The video recording below shows bargain coronal ejections from the sun. The time it takes to reach nation has been recorded at roughly 4 daytimes, by see how long it takes slew ejection of particles viewed on one day to reach the glob and produce an aurora.
From this, the speed at which the particles rifle can be calculated. ordinary time taken for particles to reach Earth = 4 days 4 days converted to seconds = 4 x 24 x 60 x 60 = 345600 seconds Average distance of Earth from sun = 149.6 x 106km Speed = keep =149.6 x 106km = 432.9kms-1 34 5600 The magnetic field lines created by th! e sun are wound into a curlicue as the sun rotates, pith that at Earth the tend at which the field hits...
