They collide with atoms of oxygen and nitrogen in the ionosphere and colored light is emitted. These colored lights make up the Northern and Southern Lights, the Aurora Borealis and Australis.
This is known as magnetic reversal when earth's magnetic poles change places.

No, it is not true. The magnetic poles may be influenced by Earth's rotation, but they are certainly not defined by it.
Charged particles are attracted to magnetic fields, and therefore are attracted to the magnetic poles of the Earth.
Only the magnetic poles wanderD.Earth's magnetic and geographic poles are generally not in the same place.Geographic poles are defined by Earth's rotation.

Because the charged particles in the solar wind streaming from the sun are attracted to the magnetic poles.
The geographical North and South Pole - not the magnetic poles.
