... Most objects normally have no overall charge, which means that they are neutral. Each atom has an equal number of protons and electrons. So each positive charge is balanced by a negative charge. As a result, there is no overall electric force on an atom. Some objects, however, can become charged. Pr ...

Since electrons are charged this corresponds to a current flowing in a wire which we know produces a magnetic field. Ferromagnetic materials are the only substances capable of being made into magnets; they are normally ...

Aurora
An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere), where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes. Different aspects of an aurora are elaborated in various sections below.
