Magnetic Field and High-Voltage Power Lines
... I am looking for a new home, and I think I found my dream house. It seems perfect, but there is something bothering me: the house is located right beside a high-voltage power transmission line. I have heard that electric wires that carry these currents create a magnetic field. So I am worried. Will ...

The solar wind
... We've learned that the solar wind travels past the Earth at well over 1.620.000 km/h. And thanks to the Earth's magnetic field, the solar wind is stopped and deflected around the Earth so that most of it does not hit our atmosphere head on. Ultra-violet rays from the sun ionize the upper atmosphere, ...

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.
