Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by external field sources,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- Magnetic induction on the working layer of the magnet remains very high,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in shaping and the ability to modify to specific needs,
- Huge importance in innovative solutions – they serve a role in computer drives, electromotive mechanisms, medical devices, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of producing nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- under perpendicular force vector (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate causes magnetic saturation, causing part of the power to be wasted to the other side.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Warnings
Implant safety
Patients with a ICD must keep an absolute distance from magnets. The magnetic field can stop the functioning of the life-saving device.
Material brittleness
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Choking Hazard
Only for adults. Small elements can be swallowed, causing severe trauma. Store away from kids and pets.
Cards and drives
Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Compass and GPS
An intense magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Skin irritation risks
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and select encased magnets.
Thermal limits
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Serious injuries
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Powerful field
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Dust is flammable
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
