NASA simulates invisible magnetic fields on the Sun.

The US Space Agency (NASA) on February 3 announced a video simulating magnetic fields around the Sun.

In this video, invisible magnetic lines are expressed, with the Sun as a giant energy sphere projecting out of space from magnetic particles, according to IB Times.

The Sun is a giant magnetic star. The material that makes it moves according to electromagnetic laws. The Sun's magnetic field causes everything, from the explosions on the Sun to produce aurora on Earth, until the interplanetary magnetic field and radiation that spacecraft must pass through when traveling. inside the solar system.

"We are not sure where the Sun's magnetic field is," said Dean Pesnell, a space scientist at NASA's Goddard Space Center in Greenbelt, Maryland. "It could be near the surface or deep inside the Sun, or on a wide range."

To observe these invisible fields, scientists have to study materials on the Sun. All materials exist in plasma state, a gas-like state but at very high temperatures and only charged particles exist.

The Sun's magnetic system is thought to have an operating cycle of about 11 years.

When these particles move, under the effect of very high temperatures from the fusion of nuclei at the center of the Sun, they create magnetic fields. This magnetic field then negatively affects the motion of charged particles. This system is called "solar generator" , according to researchers.

They combined observations and measurements of magnetic field strength and direction at the Sun's surface with insights into the magnetism and movement of the Sun's material to discover unknowns and magnetic simulations. Sun school.

The Sun's magnetic system is thought to have an operating cycle of about 11 years. For every eruption, the magnetic field flattened a bit, until the simplest state was reached, the researchers said.

Once in this state, called the "Minimum Sun" state , the explosions will be least likely to occur. After that, the magnetic field will become stronger and more complex over time, until it reaches the "Maximum Sun" state . The maximum time between two states is about 11 years.

"In the maximum state, the Sun's magnetic field has a very complex shape with many small structures, which are active regions," Pesnell said.

"At a minimum, the magnetic field is weaker and concentrated at the poles. This is a fairly flat structure and does not form sunspots".

Researchers can observe how the solar magnetic field changes, intensifies and weakens from January 2011 to July 2014. In 2011, three years after reaching the minimum state, the magnetic field focused near the poles. By 2014, the school was more confused and disorderly, creating conditions for phenomena such as fire ears and flower eruptions .
