Strengths and weaknesses of rare earth magnets.
Pros
- Their strength remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by external field influence,
- In other words, due to the reflective finish of silver, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom forming and adjusting to precise requirements,
- Significant place in modern technologies – they are commonly used in data components, drive modules, precision medical tools, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- using a base made of high-permeability steel, acting as a magnetic yoke
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an polished touching surface
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Distance – existence of any layer (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Precision electronics
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Crushing force
Large magnets can crush fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Sensitization to coating
It is widely known that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands or opt for coated magnets.
Warning for heart patients
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Electronic hazard
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Do not give to children
Product intended for adults. Tiny parts can be swallowed, leading to serious injuries. Store out of reach of children and animals.
Powerful field
Be careful. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Dust explosion hazard
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this risks ignition.
Magnets are brittle
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.
Maximum temperature
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
