10mm (25/64") Neodymium Magnet Sphere – N35 Grade 

Key Features:

• Diameter: 10mm (Approx. 25/64" or 0.394in)
• Magnet Grade: N35
• Pull Force: Approx. 3.39 lbs
• Coating: High-luster Nickel-Copper-Nickel (Ni-Cu-Ni) triple plating
• Magnetization: Diametrically magnetized (Poles on opposite sides of the sphere)

Material Description:

Our 10mm N35 spheres are designed for users who need a magnet that is as functional as it is aesthetic. The spherical geometry provides a single point of contact, which makes these magnets feel "active" as they roll and pivot into place. The N35 grade is specifically chosen for spheres of this size to provide a reliable hold without being so powerful that they become impossible to separate or prone to aggressive shattering.

Usage Tip: Spheres are great for demonstrating magnetic poles. Because they can rotate freely, they will automatically align themselves to their opposite poles when brought together. This "self-aligning" property is perfect for modular building and experimental science projects.

Warnings and Safety Information:

• EXTREME INGESTION HAZARD: Never swallow magnet balls. If two or more are swallowed, they can attract through organ walls, causing fatal internal injuries. Keep strictly away from children and pets.
• Medical Safety: Keep away from pacemakers. The moving magnetic field of a sphere can easily interfere with implanted medical devices.
• Brittleness: While they look like steel ball bearings, they are made of brittle ceramic. Avoid letting them "clack" together with force, as they can chip or shatter.
• Electronics: Keep away from traditional hard drives, mechanical watches, and magnetic strips.

Applications:

• Educational science experiments and classroom demonstrations
• Building complex geometric magnetic sculptures and desktop toys
• Creative DIY jewelry closures and magnetic fashion accents
• Industrial reed switch activation and non-contact sensors
• DIY magnetic "mixers" and laboratory stirrers
