PHYSICS Lecture Notes - Lecture 3: Space Weather, Partial Derivative, Electric Field
Document Summary
Space physics is a field of study that focuses on the behavior and properties of plasma and electromagnetic fields in space. This field is essential for understanding space weather, the interaction between the earth"s magnetic field and the solar wind, and the behavior of other planets and stars. In this note, we will explore the key concepts, theories, and formulas in space physics: maxwell"s equations: maxwell"s equations describe the behavior of electric and magnetic fields. They are: permittivity of free space: faraday"s law: derivative with respect to time, ampere"s law, gauss"s law for electric fields, gauss"s law for magnetic fields: E = / 0 where e is the divergence of the electric field, is the charge density, and 0 is the. B = 0 where b is the divergence of the magnetic field. E = - b/ t where e is the curl of the electric field, b is the magnetic field, and / t represents the partial.
