Strong magnetic balls made of neodymium. Ball magnets are super magnets in different sizes and strengths from 2 mm diameter to 40 mm diameter. They are strong magnets for glass magnetic boards, magnetic boards, whiteboards, refrigerators and experiments.

A neodymium magnet in the shape of a ball is called a magnetic ball. Neodymium magnets in general are particularly characterized by their strong magnetic force, which ensures that even very small magnets can hold heavy weights. Even a single ball magnet can hold several pieces of paper on a metallic surface. Their alloy also gives neodymium magnets a high-quality appearance. It is therefore important to avoid repeatedly allowing individual magnetic balls to collide with each other too strongly, otherwise the coating will loosen and the magnet may shatter.

Chrome-plated neodymium ball magnets are perfect for fixing and positioning. They are used, for example, in the home, in model making or in the office. Bar magnets are easy to handle; due to their shape, they develop high adhesive forces and are still easy to separate. Neodymium magnets are currently the strongest permanent magnets and are made of iron and boron (NdFeB).

What are magnetic balls used for

Due to their strong adhesive force and handy shape, magnetic balls are used in many areas of life. A magnetic ball is often used not only in industry, research or technology - people use magnetic balls in everyday life, for example:

• As an aid for attaching documents or posters to whiteboards, blackboards or flipcharts
• In the hobby sector for miniature or model building,
• As fridge magnets to stylishly attach photos, postcards or drawings
• As teaching and learning aids in schools and universities or for decorative purposes and as works of art.

Neodymium ball magnets are super magnets and have a very large magnetic force. They are known as desk toys among magnets and are great for experiments, model building and as “neocubes” for stress relief. You can also recreate models of molecules or create unique pieces of jewelry such as necklaces and bracelets. The magnetic balls get their silver color from a nickel-plated, chrome-plated or colored surface.

Magnet force

The forces have been determined at room temperature on a plate in polished steel (S235JR according to DIN 10 025) with a thickness of 10 mm (1kg ~ 10N). A maximum deviation of -10% compared to the specified value is possible in exceptional cases. Value is exceeded in general. Depending on the type of application (installation situation, temperatures, counter anchor etc.) the forces can be influenced enormously.
