Advantages and disadvantages of neodymium magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets are distinguished by exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
- Thanks to the shiny finish, the plating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- Magnets have exceptionally strong magnetic induction on the working surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the option of precise molding and customization to specialized solutions, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Universal use in advanced technology sectors – they are utilized in data components, electromotive mechanisms, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- using a plate made of low-carbon steel, functioning as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by even structure
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Handling guide
Before use, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Safe distance
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Precision electronics
GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Risk of cracking
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Do not overheat magnets
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. Damage is permanent.
Keep away from children
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are tragic.
Danger to pacemakers
For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Dust is flammable
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Physical harm
Large magnets can break fingers instantly. Do not put your hand between two attracting surfaces.
