... Some metals, for example iron, steel, cobalt and nickel, are magnetic. A magnet will attract them. If you drop some steel pins on the floor you can pick them up using a magnet. A magnetic force is an example of a non-contact force, which acts over a distance. In Figure 5.4, you can see a bar magnet ...

Can a Fast-Mode EUV Wave Generate a Stationary Front?
... that Nitta et al. (2013) focused on the fastest moving EUV wave and ignored any slowly moving waves behind in each event of their sample. Therefore, in our understanding, most of the EUV waves in their paper correspond to the fast-mode wave/shock wave, rather than the classical diffuse “EIT waves”. ...

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.
