Abstract: Electromagnetism，as a pivotal branch of physics，holds profound and far-reaching significance．Electric
field strength，a fundamental physical concept in electromagnetism，is often challenging for students to comprehend
due to its Abstract:nature，mathematical complexity，and counterintuitive physical properties，which make it difficult
to visualize the electric field intensity generated by charged objects in space．This paper leverages Mathematica
software to enhance students＇ understanding of electric field distributions generated by charged objects through the
following visualizations:drawing electric field lines of an electric dipole，Plotting the relationship between electric
field strength and distance for a uniformly charged thin rod along its extension line and perpendicular bisector，
creating an animated visualization of the electric field intensity along the axis of a uniformly charged ring．These
approaches aim to improve learning efficiency，familiarize students with advanced digital learning and research tools，
and cultivate their innovative capabilities．
