Energeticelectrons,whoseenergyisgreaterthantenskeV,playacrucial role in the magnetosphere. They can interact with satellites and cause significant space weather effect. The precipitation of such electrons into the ionosphere is a crucial loss process in their dynamics. Investigating the precipitation patterns of energetic electrons and the mechanisms behind these characteristics is essential in understanding the dynamics of energetic electrons. The Low‐Earth Orbit FY‐3E satellite provides simultaneous high‐quality measurements of magnetic fields and tens to hundreds of keV electrons, making it possible to study the precipitation of energetic electrons accurately. Based on observations of electrons from 40 to 600 keV between July 2021 and May 2024, we analyzed the precipitation patterns on dawnside and duskside and their correlation with geomagnetic activities and solar wind conditions. We found various precipitation patterns for different energy electrons, attributed to several precipitating mechanisms. Our results provide valuable insights into the precipitation of energetic electrons in the magnetosphere, enhancing the understanding of electron dynamics in the magnetosphere‐ionosphere coupling process.
