3mm Dia Neodymium Sphere Magnets N35 Small Magnetic Balls Rare Earth Ball Magnets Tiny Balls Neocube Puzzle Toys

These 3mm magnetic balls spheres magnets are tiny! They are small but surprisingly strong, despite their diminutive size.

These precision neodymium sphere magnets are available in either 3mm or 25mm diameter. They are commonly used in sculptures, artistic displays and experiments. The power of these magnets should not be underestimated; there is a risk that these magnets will chip and break if they are allowed to slam together. Because of this they are not suitable for children and should not be bought as toys.

Neodymium magnets are the most powerful of all permanent magnets. They are often known as “Super Magnets”.

They are used in applications where the strongest magnetic force is required from the smallest possible volume of magnet material.

Even small neodymium magnets have a surprising amount of magnetic force and they are capable of lifting in excess of 1,000 times their own weight. A neodymium disc magnet weighing only 2 grams can lift a steel block weighing over 2,000 grams!
