Charged particles in motion generate both electric and magnetic fields simultaneously. The study of these fields often focuses on one at a time due to historical inertia, as electric and magnetic forces were discovered through different phenomena. This approach also serves educational convenience, allowing students to grasp simpler concepts before tackling more complex scenarios. Initially, students learn about isolated electric or magnetic fields, which prepares them for advanced topics involving the unified electromagnetic field. Ultimately, understanding both fields together is essential for a comprehensive grasp of electromagnetism.
