context: The Zeeman effect is the phenomenon of splitting of the spectral lines of a source under the influence of a fixed magnetic field into several lines; that is, the Zeeman effect splits the spectrum lines into parallel lines when the light source is placed in a strong magnetic field. [1] [2] [ 3] It is an effect dating back to the Dutch scientist Peter Zeman who discovered this phenomenon in 1896 AD. This effect is similar to another effect called the Stark effect, which is splitting the spectrum lines into several lines if the light source is exposed to an electric field.
