A moving charge creates a magnetic field due to its motion through space. According to classical electromagnetism, specifically Ampère's law and the Biot-Savart law, any electric charge in motion generates a magnetic field that encircles the path of its movement. This phenomenon is fundamental to the principles of electromagnetism and explains several important concepts, such as the operation of electric motors and generators.

In contrast, an electric field is produced by a stationary charge, while an electrostatic field is associated with static charges at rest. A gravitational field is generated by masses, not charges. Thus, the only field specifically linked to the motion of an electric charge is the magnetic field. Understanding this principle is crucial for grasping how electric currents interact with magnetic fields in various applications, including electromagnetic devices and wireless communication systems.
