# How far does the Sun’s magnetic field stretch?

How far does the Sun’s magnetic field stretch? It influences the motion of charged particles well beyond the orbits of the known planets, to distances of around 75-100 times the distance of the Earth to the Sun.

Where does the Sun’s magnetic field end? To a good approximation, the sun acts like a giant bar magnet with the North pole on one end, the South pole on the other end, and both magnetic poles aligned with the axis of rotation. (This is very similar to how the earth has an overall magnetic field due to its rotation. )

How large is the Sun’s magnetosphere? As the largest structure in the solar system, the magnetosphere is about 21 million kilometers (12 million miles) wide. That’s 150 times wider than the planet itself and almost 15 times wider than the sun.

Does the Sun have a magnetic field? The sun’s magnetic field has two poles, like a bar magnet. The poles flip at the peak of the solar activity cycle, every 11 years. A solar wind composed of charged particles carries the magnetic field away from the sun’s surface and through the solar system. The sun is not a solid ball, but rather like a fluid.

## How far does the Sun’s magnetic field stretch? – Additional Questions

### How strong is suns magnetic field?

The Sun has a very large and very complex magnetic field. The magnetic field at an average place on the Sun is around 1 Gauss, about twice as strong as the average field on the surface of Earth (around 0.5 Gauss).

### How does Sun get magnetic field?

It is widely believed that the Sun’s magnetic field is generated by electrical currents acting as a magnetic dynamo inside the Sun. These electrical currents are generated by the flow of hot, ionized gases in the Sun’s convection zone. We know a lot about the Sun’s magnetic dynamo. It has a 22 year cycle.

### Does the Sun have an electric field?

The sun’s electric field arises from the interaction of protons and electrons generated when hydrogen atoms are stripped apart in the intense heat generated by fusion deep within the sun.

### What would happen if the Sun lost its magnetic field?

The magnetic field helps shield us from things in space (like rocks and solar energy) that come too close. If it disappears it will make space rocks more likely to collide with us, and harmful radiation from the Sun will not be deflected away and could actually strip the ozone layer away.

### Does the Sun’s magnetic field affect the Earth?

No. The only influence that the Sun’s magnetic field has on the Earth is through the energy released by solar flares and coronal mass ejections. These events are caused by changes in the Sun’s magnetic field structure.

### When was the last time the Sun’s magnetic field flipped?

When did the magnetic poles flip in Solar Cycle 24? Both poles have now flipped. The north pole changed its polarity from positive to negative and the south pole changed from negative to positive. Scientists believe the north pole finished the change in June 2012 and the south pole change happened in July 2013.

### What will happen if Earth’s magnetic field flips?

If Earth’s magnetic field were to decay significantly, it could collapse altogether and flip polarity – changing magnetic north to south and vice versa. The consequences of this process could be dire for our planet. Most worryingly, we may be headed right for this scenario.

### How often does the Sun’s magnetic field flip?

Unlike the Earth however, the Sun’s global dipole magnetic field flips or reverses polarity every 11 years around the maximum phase of each 11 year solar cycle.

### Can the Earth flip upside down?

Fortunately, short of being hit by some vast celestial body, the Earth can’t flip over, as the Moon’s gravity field keeps our planet on a fairly even keel. But the magnetic poles can, and do, undergo complete reversals, most recently around 780,000 years ago.

### What happens when the Suns poles switch?

The flip-flopping of the Sun’s magnetic field takes place at the peak of each solar activity cycle when the Sun’s internal magnetic dynamo reorients itself. When the field reversal happens, the magnetic field weakens, then dies down to zero before emerging again with a reversed polarity.
