Understanding Magnetic Poles and Field Lines with a U-Shaped Magnet #3755500 (License: Personal Use)

This diagram depicts a red U-shaped (horseshoe) magnet with clearly labeled north (N) and south (S) poles on gray end caps. Yellow curved lines represent magnetic field lines emanating from the north pole and converging at the south pole, demonstrating the direction and shape of the magnetic field in space around the magnet.

Used in educational physics content, STEM lesson plans, and science websites to explain magnetism fundamentals; matches user intent for visual learning about magnetic poles, field lines, and dipole behavior.
