What Is a Magnet? Simple Diagram Explaining Magnetic Fields #168230 (License: Personal Use)

This black-and-white line drawing depicts a traditional U-shaped (horseshoe) magnet, emphasizing its north and south poles and the curved magnetic field lines that emanate from one pole to the other. The jagged outer lines represent the invisible magnetic flux, illustrating how magnetic force extends through space. The sketch-style rendering makes it ideal for educational materials where clarity and simplicity are prioritized over photorealism.

Used in science education websites, physics lesson plans, and STEM outreach content to explain basic magnetism concepts; targets students, teachers, and curious learners seeking foundational knowledge.
