    Neodymium magnets are a remarkable achievement in modern technology. Despite their compact size, these magnets are extremely strong and capable of supporting significant weight. Their affordability also makes it easy to acquire a large quantity of these magnets. These versatile magnets are ideal for securely holding photographs, memos, and other important objects in place on metallic surfaces without being noticed.

    One of the most intriguing features of neodymium magnets is how they behave in the presence of other magnets, providing limitless possibilities for scientific exploration and experimentation. When purchasing these magnets, it's critical to note that they are graded based on their maximum energy product, which reflects their magnetic flux output per unit volume. A greater value corresponds to a more potent magnet.

    These neodymium magnets feature countersunk holes and are covered in three layers of nickel, copper, and nickel, which helps to prevent corrosion and provide a polished appearance, substantially extending the lifespan of the magnets. The countersunk holes also allow the magnets to be secured to non-magnetic surfaces using screws, extending their range of applications. These magnets have a diameter of 1.25 inches and a thickness of 0.25 inches, with a countersunk hole diameter of 0.22 inches.

    Neodymium magnets with holes are robust and dependable, suitable for a wide range of applications such as tool storage, photograph displays, refrigerator magnets, scientific experiments, locker suction, or whiteboard magnets. However, caution must be exercised when using these magnets since they can collide with one another with enough force to chip or shatter, causing harm, especially to the eyes.

    If you are not satisfied with your purchase, rest assured that you can return it for a full refund.
