Alnico Cylindrical Magnet Pair with Keepers, 50 x 12mm

These Alnico cylindrical magnets measure 50 x 12mm (approximately 4 inches long) and are supplied as a pair with keepers and a storage box. Pink dots on the ends denote opposing poles for easy identification of like poles during experiments. Alnico (aluminum-nickel-cobalt) alloy provides a strong, stable magnetic field that resists demagnetization over time. The cylindrical shape allows students to visualize and physically experience the push and pull of magnetic fields as the magnets interact. The included keepers bridge the poles during storage to maintain magnetic strength. Suitable for physics experiments covering magnetic fields, attraction, repulsion, and pole identification.
