An ideal Fermi gas is a state of matter which is an ensemble of many non-interacting fermions. Fermions are particles that obey Fermi–Dirac statistics, like electrons, protons, and neutrons, and, in general, particles with half-integer spin. These statistics determine the energy distribution of fermions in a Fermi gas in thermal equilibrium, and is characterized by their number density, temperature, and the set of available energy states. The model is named after the Italian physicist Enrico Fermi.

This physical model can be accurately applied to many systems with many fermions. Some key examples are the behaviour of charge carriers in a metal, nucleons in an atomic nucleus, neutrons in a neutron star, and electrons in a white dwarf.

I would like to ask you, if you want to tell me? in the corona of the sun eclipses are created by the hydrogen of the sun which is approved by the high temperature and they become plasma?

NASA: Physically, the chromosphere begins near the surface of the photosphere with a temperature near 4700 Celsius and a density of 1017 particles/cm3 (2x10-4 kg/m3), and at its highest level reaches a temperature near 25,000 Celsius and a lower density of 1010 particles/cm3 (2x10-11 kg/m3). But rather than being just a homogenous shell of plasma, it resembles the troposphere of our own planet Earth with complex storms and other phenomena roiling its volume from minute to minute.

The reason for this is that the magnetic fields formed at or below the surface of the photosphere are not confined to the solar surface, but extend through-out the chromosphere. Magnetic arcs, prominences and other carpets of magnetic activity repeatedly form and dissolve, releasing energy and stirring up the chromospheric plasma. Solar physicists call the chromosphere and the narrow region above it the solar ‘interface region’. It is a complex zone of plasma and magnetic field, which transmits matter and energy between the photosphere and the corona.

"magnetic activity repeatedly form and dissolve, releasing energy and stirring up the chromospheric plasma."

"with a temperature near 4700 Celsius"

At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature. Heat the magnet even more, and it will melt, and eventually vaporize.

Note: A dipole is a separation of opposite electrical charges. A dipole is quantified by its dipole moment (μ). A dipole moment is the distance between charges multiplied by the charge. ... The distance separating opposite electrical charges also affects the magnitude of the dipole moment.

In classical physics, the magnetic field of a dipole is calculated as the limit of either a current loop or a pair of charges as the source shrinks to a point while keeping the magnetic moment m constant. For the current loop, this limit is most easily derived from the vector potential.

Since atoms are surrounded by moving electrons, most of them act like little magnets themselves. ... All magnets have both a north and a south pole, which classifies them as dipoles. It is impossible to create a magnet with only one pole. Similar poles always repel each other, and opposite poles always attract.

An electric dipole deals with the separation of the positive and negative charges found in any electromagnetic system. A simple example of this system is a pair of electric charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.)

In Summary. The dipole magnets are used to bend the path of the electrons as they travel around the ring. Charged particles travelling in a magnetic field change direction. The stronger the current applied to the electromagnets, the more the electron beam is bent.

An ideal dipole consists of two opposite charges with infinitesimal separation. ... A key point is that the potential of the dipole falls off faster with distance R than that of the point charge.

The dipole consists of two point electric charges of opposite polarity

Negative affect is a broad concept that can be summarized as feelings of emotional distress (Watson, Clark, & Tellegen, 1988); more specifically, it is a construct that is defined by the common variance between anxiety, sadness, fear, anger, guilt and shame, irritability, and other unpleasant emotions.

Electron promotion is when an electron absorbs a photon to jump from a low energy level orbital to a higher energy orbital, hence “promotion.” This can only happen if the photon energy matches the energy difference of the orbitals.

In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum). Excitation is an elevation in energy level above an arbitrary baseline energy state. In physics there is a specific technical definition for energy level which is often associated with an atom being raised to an excited state.[citation needed][definition needed] The temperature of a group of particles is indicative of the level of excitation (with the notable exception of systems that exhibit negative temperature).
