Magnetic Field Lines Around a Bar Magnet - Physics Visualization #3755493 (License: Personal Use)

This schematic depicts a red bar magnet with clearly marked north (N) and south (S) poles, surrounded by concentric blue curved lines representing the magnetic field. The field lines emerge from the north pole, loop externally, and re-enter at the south pole, illustrating the dipolar nature of magnetic fields. Arrows on the lines indicate the direction of the magnetic force on a hypothetical north test pole.

Used in educational resources, physics textbooks, and online learning platforms to teach electromagnetism fundamentals; matches user intent for visualizing magnetic fields or understanding pole behavior.
