SM-0478104 Red-Green Polarity Marked AlNiCo Long Cylinder Magnets
Features
Premium AlNiCo Alloy with Superior Thermal Stability: Engineered from high-grade sintered AlNiCo, these long cylinder magnets maintain stable magnetic performance across a wide temperature range, with minimal magnetic loss even at continuous operating temperatures up to 500°C. This makes them ideal for use in educational labs and workshop environments where temperature fluctuations may occur, ensuring consistent magnetic output during every experiment.
Red-Green Polarity Marking for Clear Visual Identification: The two-tone red-green enamel paint scheme is purpose-designed to mark the north and south poles, a critical feature for teaching magnetic polarity, demonstrating attraction/repulsion, and constructing magnetic circuits. This eliminates the need for additional testing equipment, streamlining setup and reducing errors in educational activities, while the vivid colors enhance visibility and student engagement.
Precision D9.5×200mm Slender Cylindrical Form Factor: The long, thin rod geometry (9.5mm diameter, 200mm length) is precision-machined to strict dimensional tolerances, creating a strong, uniform axial magnetic field that is ideal for demonstrating magnetic field lines, conducting compass experiments, and exploring basic magnetism principles. The slender design also makes the magnets lightweight and easy to handle, perfect for classroom demonstrations and student use.
Glossy Enamel Coating for Durability & Corrosion Resistance: The smooth, durable red and green enamel paint provides robust protection against oxidation, scratches, and environmental wear, extending the service life of the magnets in high-use educational settings. The coating also creates a non-slip, easy-to-clean surface that maintains its appearance even with frequent handling, making these magnets a long-lasting investment for schools and labs.
Consistent Magnetic Performance & Low Temperature Drift: Sintered AlNiCo exhibits a very low temperature coefficient of remanence, meaning its magnetic flux density changes minimally with temperature fluctuations. This stability ensures reliable, repeatable results in educational experiments, even in environments with variable room temperatures, allowing students to observe consistent magnetic behavior.
High Mechanical Durability & Impact Resistance: The dense sintered AlNiCo structure offers excellent mechanical strength, while the enamel coating adds an extra layer of protection against chipping and cracking during accidental drops or rough handling. This durability makes these magnets suitable for frequent use in classrooms and student-led experiments, reducing the risk of damage and replacement costs.
Versatile Educational Application Compatibility: These red-green painted AlNiCo long cylinder magnets are widely used in science classrooms, physics labs, and educational outreach programs for teaching magnetism, demonstrating magnetic fields, and exploring polarity interactions. Their clear marking, strong magnetic field, and durable construction make them ideal for a wide range of hands-on experiments and demonstrations.
RoHS-Compliant & Safe for Educational Use: Constructed from lead-free AlNiCo alloy and non-toxic enamel paint, the magnets meet international RoHS environmental standards, ensuring they are safe for use in schools, laboratories, and public educational settings. Their long operational life and low maintenance requirements make them a cost-effective choice for educational institutions.
