Q # 1. The potential is constant throughout a given region of space
... Ans. The magnitude of magnetic force on a charge particle can be expressed as: Where θ is the angle between B and v. So if the particle moves in a straight line through some region of space then it means that the charge particle is not experiencing magnetic force which might be due to one of the fol ...

Magnetostatics Analysis, Design, and Construction
... We have found that a compromise between simplicity and efficiency can be achieved if a metal bottle cap is used instead of the two steel parts. The magnetic field, while not as confined as in the previous case, is still concentrated near the coil, as seen in Fig. 8. Because this simple design uses ...

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.
