Description
HS Magnet’s Alnico 5 Educational Magnets (50 × 10 × 5 mm) are specially designed for clear polarity identification and long-term reliability in science classrooms, laboratories and hobby projects. Each bar magnet is precision-sintered from Alnico 5 alloy, then color-coded with red and blue epoxy paint to denote north and south poles—ideal for hands-on learning and magnetism experiments.
