Magnetic spheres made of neodymium - all-rounders for the home and office

In our range, we can offer you 9 different sizes of neodymium magnetic spheres (with a diameter of Ø 3 mm to Ø 30 mm). Magnetic spheres are a wonderful toy. Whether in your hand, on the memo board or in your pocket - a must. However, you should not let the spheres collide together too often. The magnetic pressure at the contact points is quite high and can therefore lose the coating. These sphere magnets are not suitable as toys for children. The possible choking hazard for children under 36 months is therefore a risk. Since the magnetic spheres in the intestine attract to each other, they no longer can leave the body naturally and can pinch the sensitive tissue and thus lead to serious injuries.

Neodymium magnetic spheres- what distinguishes this special alloy?

The sphere magnets, which you can buy from our shop, are made of a very special material: "Neodymium" (NdFeB). The chemical element is one of the "rare earths" and is the basis for the currently strongest magnets in the world. However, since it alone is not too stable, it is combined with iron and boron in magnet production. The resulting alloy is particularly susceptible to rust. Air humidity is already sufficient to damage the mixture. That is why the sphere magnets that we offer in our shop are finished with a special coating made of nickel, chrome or gold. This is how our customers receive top quality magnetic spheres. Compared to samarium-cobalt magnets, these are characterized by their comparatively low price and have the advantage of a ten times higher adhesive force than ferrite magnets. In addition, they are very durable and do not lose their magnetic properties even after years, which is why they are also called permanent magnets. Neodymium magnets (NdFeB) only lose their magnetic properties at temperatures above 80 ° Celsius - however, they can be used for years at home without any problems.

Magnetic spheres and their different areas of application

Due to their wide range of uses, our sphere magnets are the perfect everyday helper. Whether in your free time, at home or in the office: once you have tried our magnetic spheres, you will no longer want to do without the small all-rounders. In order to illustrate how you can use our magnets, we will show you a few possible uses below.

Use magnetic spheres for the whiteboard or memo board

Our sphere magnets are suitable for all those who would like to put their notes in order. You can attach important memos, but also pictures of your last family trip, postcards from friends, children's timetables or the flyer of your favorite delivery service to a metal memo board or whiteboard with just one hand. The adhesive force of the magnets is astonishing: even our smallest sphere magnet holds a weight of about 130 grams, even though it weighs only 0.1 gram and is only about as big as the head of a match with a diameter of three millimeters. With larger specimens of the round memo board magnets, the weight that holds the sphere on suitable surfaces increases to as much as 23 kilograms! With a weight of just 254 grams, our largest magnetic sphere holds more than 90 times its own weight. The reason for the high adhesive force of the sphere magnets lies in their mysterious interior: They are made of neodymium, a material from which the world's strongest super magnets are also made of. They are also finished with a nickel coating to protect the magnets from rust. Their advantage over pins and nails is that the magnets do not leave any permanent changes, such as holes, on your boards. If you no longer need your notes, you can easily pull off the easy-to-move magnetic spheres without leaving any residue on the surface. Even on your fridge, which becomes a practical memo board in the kitchen thanks to the little everyday helpers.

Create sculptures from magnetic spheres and non-magnetic spheres

In addition to their practical use, our magnetic spheres also have an aesthetic side. With them, you can live out your artistic side and create entire sculptures. There are no limits to creativity, especially in connection with non-magnetic steel spheres. Whether cubes, spheres, figures, and abstract works of art or other structures - everything is possible. You can achieve special effects by combining magnets with different coatings and thus different colors. In our shop, you can get - depending on the size requirements - magnetic spheres with chrome, gold and nickel coating.

Magnetic spheres as desk toys

Small sphere magnets are also known as desk toys under names such as Neocube or BuckyBalls. Treat yourself to a short break at work, in which you assemble the small spheres into different forms of "neocubes", and escape your everyday life for a few minutes. The toy is the perfect stress killer and a decorative accessory in the office. Once you have tried it, you will not want to put the Neocubes down

Make models of molecules with magnetic spheres

Our magnetic spheres are also ideally suited for use in science, research and teaching: In connection with cube and bar magnets, detailed models of different molecules or atoms can be created. These are perfect as decorations in the office or laboratory, to clearly, depict teaching material or present as three-dimensional exhibits in exhibitions. No matter where you use our magnetic spheres, they are always an eye-catcher.

Magnetic spheres for jewelry

The use of sphere magnets as jewelry is huge. They can be attached to a disc magnet, which you also purchase, next to the spherical magnets in our shop. If you stick the disc magnet to a neutral ring, you get a unique piece of jewelry that can be constantly changed by the moving spheres. It is also possible to string the spheres together to create unique chains and bracelets. You can create special effects by alternating the sphere magnets with other magnets. For example, cube or ring magnets are suitable for this. Men can also use our sphere magnets as subtle pieces of jewelry. As cufflinks, they give to a very chic shirt the final addition. In addition, the small magnets on bracelets and chains can be used as a flexible magnetic clasp. With little effort, it is possible to attach the spheres to a chain or a bracelet with our magnetic instant adhesive glue. Therefore, you can easily lock your jewelry without having to thread a delicate closure. This not only saves time, but also nerves.

Magnetic spheres: Frequently asked questions

Our magnetic spheres are ready for use immediately after delivery and are easy to use. Nevertheless, questions may arise when dealing with the sphere magnets. We would like to answer some of them for you here.

Which magnetic spheres are right for me?

When choosing the magnetic spheres, you should always pay attention to what you want to use them for. As a rule of thumb, the larger the magnet, the greater its adhesive force. When using the sphere magnets on memo boards or whiteboards, you should think about what you want to attach before buying. Which weight can hold which magnets is described in more detail in the shop for the individual products. When using the spheres for works of art, models or jewelry, you should evaluate the appearance of the spheres in addition to the adhesive force. These are available with various coatings that have no effect on the adhesive force. This is about what you like best. If you have further questions about the use of magnetic spheres, our magnetshop.com experts will be happy to advise you.

That is why you should not let magnetic spheres collide together

To increase the durability of the sphere magnets, they are overdrawn with a coating of chrome, gold or nickel. This prevents the magnetic core made of neodymium, boron and iron from rusting. The coating also gives the spheres a particularly high-quality appearance. If you let the spheres collide, a particularly high magnetic pressure is created at the contact points. Under certain circumstances, this can lead to detaching of the coating (nickel). This significantly reduces the durability of the spheres. A single collision of two magnets is of course not a problem here. Only with frequent collisions, negative effects on the coating result.

How should I store the magnetic spheres?

Due to their round shape, sphere magnets easily roll away. That is why we recommend storing them properly in a bag or a box. You should also note that the magnets should not be kept near objects or devices that can be damaged by magnetism. These include television sets, EC cards, computers, electronic data carriers, hearing aids and loudspeakers. In addition, large magnets can disturb pacemakers. If you or someone in your area has a pacemaker - exercise extreme caution!

Why are magnetic spheres not suitable as toys for children?

As attractive as the sphere magnets for children may be, they are not suitable as toys for them. The reason is simple and obvious. The spheres can be easily swallowed due to their small size. If a magnet is stuck in the trachea, there is a risk of suffocation. If a child swallows several spherical metals, their strong attraction can cause them to be stuck in the intestine, and cause life-threatening injuries, such as an intestinal breakthrough. With larger spheres, the risk of accidentally swallowing them is lower - but due to their high adhesive force, they can lead to bruises, for example on the fingers. Therefore, keep our magnetic spheres out of the reach of children. We therefore only recommend special magnetic toys for use in children's rooms.

What should I do if my child has swallowed a magnetic sphere?

If an emergency does occur and your child has swallowed a magnet, you should immediately consult a doctor. Using an X-ray examination, the exact position of the foreign body in the body can be determined and all necessary measures can be initiated.
