Description
Product Overview
The Eisco Labs Alnico Bar Magnet set includes two 6‑inch long, 0.5‑inch wide magnetic bars crafted from high‑grade Alnico alloy, a material renowned for its exceptional magnetic stability and resistance to demagnetization. Each bar measures 6 x 0.5 x 0.25 inches and weighs approximately 8 ounces, providing a solid, dense feel that translates into a reliable magnetic pull across a range of temperatures. The magnets are encased in a corrosion‑resistant steel housing that protects the Alnico core while allowing the magnetic field to extend outward uniformly. With a first‑available date of January 24, 2014, these magnets have a proven track record in both industrial and educational settings, ranking #74 in the Alnico Magnets subcategory on Amazon. Their dimensions and weight make them easy to handle, store, and integrate into a variety of applications, from material handling equipment to physics experiments. The product is not discontinued, ensuring continued availability for repeat orders and long‑term projects.
Usage
These Alnico bar magnets are designed for versatility. In industrial environments, they serve as reliable lifting aids for ferrous components, magnetic separators for scrap metal processing, and alignment tools for precision assembly lines. Their strong, stable field makes them suitable for holding metal plates in place during welding or machining operations, reducing the need for additional clamps. In educational settings, the magnets are perfect for physics classrooms, allowing students to explore magnetic field lines, force interactions, and the principles of magnetism through hands‑on experiments. The 6‑inch length provides enough surface area for clear demonstrations while remaining safe for student handling. Additionally, the magnets can be employed in hobbyist projects such as DIY magnetic levitation devices, custom magnetic tool holders, and experimental sensor rigs. Their durable steel casing ensures they withstand repeated use, accidental drops, and exposure to workshop environments without losing performance.

FAQ
What is the holding force of the 6‑inch Alnico bar magnet?
The exact holding force depends on the material it is attracted to and the distance between the magnet and the target surface. In typical steel applications, the magnet can hold several pounds of weight when in direct contact.
Are these magnets safe for classroom use?
Yes. The magnets are encased in a steel shell that prevents direct contact with the Alnico core, reducing the risk of injury. They are also sized for easy handling by students under supervision.
Can the magnets be used in high‑temperature environments?
Alnico retains its magnetic properties up to approximately 500°F (260°C). The steel housing also tolerates elevated temperatures, making the magnets suitable for many industrial processes.
Do you offer custom sizes or shapes?
Eisco Labs provides custom magnet solutions for bulk orders. Contact our sales team with your specifications, and we will work with you to develop a tailored product.
What is the warranty period for these magnets?
All Eisco Labs Alnico magnets come with a one‑year limited warranty covering manufacturing defects and premature loss of magnetic performance.
