Did the sun reverse polarity?

The whole sun's magnetic polarity switches about every 11 years—though it can take much longer at times—and defines what is known as the solar cycle. Though there are some regions on the sun that switch polarity more often (such as the poles themselves), most of its surface remains stable for many decades or even centuries at a time.

When this happens, we see changes in the aurora and elsewhere on earth. The magnetism of our planet causes these particles to swirl around in space, so if the direction of the main magnetic field on earth changes, they will be affected by this new configuration. If it gets more negative, they will be attracted to earth; if positive, they will be repelled by it. This is why variations in the intensity of the aurora are associated with solar activity.

However, not all aspects of solar activity have the same impact on earth. For example, high-speed particles from supernovae explosions reach earth even though the star itself has no effect on us. Also, electromagnetic radiation from the sun is responsible for radio blackouts and other problems for astronauts living in spacecraft, but when the sun is active, these effects can be avoided by moving into a safe location immediately before or after making contact with other people or equipment.

Does the sun change polarity every 11 years?

The Sun's worldwide dipole magnetic field, unlike the Earth's, flips or reverses polarity every 11 years around the maximum phase of each 11-year solar cycle. The polarity of the solar polar fields in both hemispheres reverses or shifts to the opposite polarity during the reversal. The shift is not complete, however; there are still regions of constant north and south magnetic poles on the Sun.

During a reversal, the northern hemisphere has the responsibility of keeping global temperatures cool by releasing more radiation into space than it absorbs from the atmosphere and oceans. The southern hemisphere takes over this role after the reversal when the north becomes warmer. This is because all of the conflict sites in the world are in the northern hemisphere, so if we want peace to prevail on earth, then we should be helping the Sun bring about another magnetic pole reversal.

The last time the Sun shifted from positive to negative magnetic poles was around 1750. Before that time, it switched back and forth between positive and negative every 22 years or so. The next switch is expected to occur around 2200. After that, the Sun will continue to become more and more negative until it reaches zero in approximately 5 billion years when it will collapse into itself causing a massive explosion that may destroy Earth.

Polarity refers to the direction of the magnetic field at any given location on the Sun.

Does the sun’s magnetic field reverse?

Every 11 years, the polarity of the sun's magnetic field changes. At the apex of each solar cycle, the sun's inner magnetic dynamo reorganizes itself. This is a natural occurrence in the solar cycle. A reversal of the sun's magnetic field is a huge occurrence. It has serious implications for life on Earth.

The last major reversal occurred about 550 AD and left us with an old version of the sun's magnetic field. Since then, the sun's magnetic activity has been declining. Now, it appears that we are close to another reversal. Some scientists believe we may already be in the midst of it. If they are right, we should see some dramatic changes on our planet within our lifetimes.

The sun's magnetic field comes from currents flowing inside its star-like body. These currents generate the field, just as a magnet generates electricity when current is passed through it. The sun goes through these cycles every 11 years or so. When this happens, the direction of the flow of current reverses, causing the field to switch polarity.

Our planet's magnetic field is generated by its own internal dynamo process. But like the sun, it also has a magnetic field due to friction between plasma (the name for gas with almost no solid particles) inside the planet. This is known as the geomagnetic field. It protects us from many dangerous particles emitted by the sun during periods of high activity.
