Magnetic Field Lines Demonstrated with Compass and Bar Magnet #293294 (License: Personal Use)

This vintage-style line drawing depicts a hand holding a string attached to a small compass needle, which traces elliptical paths above a horizontally placed bar magnet labeled with north (N) and south (S) poles. Dashed lines represent the magnetic field lines curving from the north to the south pole, demonstrating how the compass needle orients itself tangentially to these fields. The illustration emphasizes foundational electromagnetism principles taught in introductory physics.

Used in educational web pages, textbooks, or science museum exhibits explaining magnetism; targets students, teachers, and curious learners seeking visual reinforcement of magnetic field concepts.
