# How do electric and magnetic fields interact with light?

A magnet can also change the direction of an electrical current, a current of electrons. But if you point a magnet at the light, nothing happens. Light and magnetism don't interact. Static electric and magnetic fields do affect electromagnetic waves, and we can trust that mathematics works, with the sum of vectors and all that.

The conditions are studied in plasmas, for example this model. At the end of the 18th century, Benjamin Franklin, Charles-Augustin de Coulomb and others began to understand electrical phenomena. But if we modify the electric field at adjacent wavelengths so that they are orthogonal to each other, the subsequent interruption is significantly reduced. Although a magnetic field does not directly affect the photons of light, a magnet can distort the medium through which light passes and, therefore, “bend” light rays.

Siméon-Denis Poisson, Pierre-Simon Laplace and Carl Friedrich Gauss developed powerful mathematical descriptions of electrostatics and magnetostatics that are maintained today. The temperature “field” is simply a mathematical accounting of those numbers; it can be expressed based on spatial coordinates. In 1888, German physicist Heinrich Hertz succeeded in demonstrating the existence of long-wavelength electromagnetic waves and demonstrated that their properties are consistent with those of shorter wavelength visible light. This situation changed dramatically in the 1860s, when the Scottish physicist James Clerk Maxwell, in a decisive theoretical treatment, unified the fields of electricity, magnetism and optics.

A strong magnetic field can increase the effect of the object's mass on the curvature of space-time. While the understanding of light has undergone some profound changes since the 1860s as a result of the discovery of the quantum mechanical nature of light, Maxwell's electromagnetic wave model remains completely suitable for many purposes. In Faraday's time, it was known that electrical charges were the source of electric fields and that electric currents (moving charges) were the source of magnetic fields. The English physician William Gilbert began the careful study of magnetic phenomena at the end of the 16th century.

Galactic magnetic fields can align charged dust grains in interstellar dust clouds, which can polarize the starlight that passes through them. We have compelling reasons to conclude that light itself, including radiant heat and other radiations, if any, is an electromagnetic disturbance in the form of waves that propagate through the electromagnetic field in accordance with electromagnetic laws. He presented a mathematical formulation in which the values of electric and magnetic fields at all points in space can be calculated based on knowledge of the sources of the fields. The ultra-strong magnetic field or the amazing emission of X-rays and gamma rays from a magnetar would kill you.
