Neodymium magnets - why are they so strong?

Neodymium magnets, despite their sometimes small size, are considered the strongest magnets in the world. They get their neodymium power by combining several components that generate a very strong magnetic field in the right proportion. There are several types of neodymium magnets - disc, ring and plate. 

Neodymium magnets - structure, properties

A neodymium magnet is a mixture of neodymium (Nd), iron (Fe) and boron (B). The combination of these materials in the right proportion makes neodymium magnets very strong and durable. When you use the appropriate materials, they are resistant to damage and can be used at temperatures of up to 120oC. Some kinds of neodymium are resistant even up to temperatures of 230oC). The disadvantage of magnets is their tendency to corrosion, but this drawback is eliminated by applying an additional, protective coating. It is also worth noting that thanks to their high strength and small dimensions, magnets are an ideal solution in limited spaces.

Magnet N38, N42 - what does it mean?

Have you ever wondered what the combination of letters and numbers in the description of each magnet means? N38 or N42 are the so-called specifications (qualities) of the magnet materials consisting  of two parts:

• the letters N, M, H, SH, UH, define the maximum temperature at which the neodymium magnet can be used.  For example,  a magnet marked with the letter N can be used at a maximum temperature of 80°C, and H up to 120°C. 
• the numbers 38, 42 and 50 indicate the strength of the magnet and are expressed in MGOe. 

The use of neodymium magnets.

Neodymium disc magnets - are one of the strongest magnets on the market, thanks to their strength and sometimes small size, they have many technical, commercial and consumer purposes. They are used, amongst other areas, in medicine, in the construction of headphones, sensors, meters, motors and clips etc.

Plate Neodymium block magnets are used in many electronic devices, and in everyday life we ​​can come across them, for example indoors, fastenings on handbags, knife handles in restaurants, or as fridge magnets. 

Screw-on neodymium magnets - used primarily on non-magnetic surfaces, such as wood, plastic or metal. Mounting the magnet is very quick and simple, just use a screw or a countersunk screw. In our store you will find both cylindrical and plate magnets, with one or two holes.

Neodymium magnet with 3M tape - this is an ideal solution in places where attaching the magnet with screws is not possible. These can be used on glass or furniture. Their small size and huge strength make them a good solution for use in schools, offices and art studios.

Neodymium - can a strong magnet be dangerous?

The high strength of these magnets together with their small size can be risky. First of all, please keep neodymium magnets out of the reach of children, as swallowing them may be dangerous. Also, do not use magnets close to some electrical appliances, magnetic cards or computer storage data, as they may cause damage.
