U-Shaped Magnet Diagram - Magnetic Poles Explained #3280847 (License: Personal Use)

This diagram depicts a classic horseshoe or U-shaped permanent magnet, colored red with white pole caps labeled "N" and "S" to indicate the north and south magnetic poles. The shape concentrates the magnetic field between the two close poles, making it stronger than a bar magnet of comparable size. Such magnets are commonly used in educational settings to demonstrate magnetic fields, polarity, and induction.

Used in physics textbooks, science websites, and classroom presentations to illustrate magnetic polarity and field lines; matches user intent for learning basic electromagnetism concepts.
