Magnetic Field Lines Around a Bar Magnet - Physics Visualization #140933 (License: Personal Use)

This educational diagram shows a green-and-red bar magnet labeled with 'N' (north) and 'S' (south) poles at its ends. Curved black arrows represent magnetic field lines flowing outward from the north pole and looping back into the south pole, forming closed loops. A light-blue circular region highlights the area of concentrated magnetic flux surrounding the magnet.

Used in physics education websites, textbooks, and STEM learning platforms to explain magnetism fundamentals; matches user intent for visualizing magnetic fields, understanding polarity, or preparing classroom materials.
