Bar Magnet with North and South Poles - Educational Science Image #3755497 (License: Personal Use)

This rectangular bar magnet features a distinct color-coded design: the red half is labeled “N” for north pole, and the blue half is labeled “S” for south pole. The magnet appears to be coated in durable plastic or enamel, with embossed lettering for durability and visibility in classroom settings. It’s commonly used in introductory physics to illustrate magnetic dipole behavior, field lines, and attraction/repulsion principles.

Used in K-12 science curricula, university lab manuals, educational websites, and STEM outreach materials to visually explain magnetism fundamentals; matches user intent for learning, teaching, or illustrating magnetic polarity.
