Chrome Steel Bar Magnet Pair, Red/Blue, 150 x 12 x 5mm

These chrome steel bar magnets are painted blue and red to clearly indicate north and south poles. Each magnet measures approximately 150 x 12 x 5 mm, providing a convenient size for a range of classroom magnetism experiments. The low magnetic strength makes them suitable for careful, controlled experiments such as demonstrating magnetic field lines, attraction and repulsion, and compass needle deflection in physics education.
