Strengths and weaknesses of rare earth magnets.
Pros
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetism drop as a result of external fields,
- In other words, due to the smooth surface of silver, the element gains visual value,
- Neodymium magnets create maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the option of flexible molding and adaptation to unique needs, neodymium magnets can be manufactured in a variety of forms and dimensions, which amplifies use scope,
- Wide application in innovative solutions – they serve a role in hard drives, electromotive mechanisms, medical devices, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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 magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of creating threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic field
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- without any clearance between the magnet and steel
- under axial force direction (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of maximum force).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the flux to be wasted into the air.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Warning for allergy sufferers
A percentage of the population suffer from a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching might lead to an allergic reaction. We suggest wear protective gloves.
Magnetic interference
An intense magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Dust explosion hazard
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Safe operation
Be careful. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
Heat warning
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Bone fractures
Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Warning for heart patients
Individuals with a ICD should maintain an large gap from magnets. The magnetism can interfere with the functioning of the implant.
Risk of cracking
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Danger to the youngest
Absolutely keep magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
