The relationship between electric currents and the directional orientation of surrounding magnetic field lines is a fundamental law of physics (Ampère's right-hand rule) and constitutes basic common knowledge that does not require citation.
Magnetic field lines follow a circular path around an electric current, with their direction determined by the right-hand rule.
The claim describes the direction of magnetic field lines around an electric current according to the right-hand grip rule. This is a foundational, universally accepted principle of electromagnetism taught in introductory physics, making it common knowledge. Under the instructions, common knowledge claims require no citations and are designated with the COMMON_KNOWLEDGE verdict with empty index arrays.
