Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They feature excellent resistance to magnetism drop as a result of external magnetic sources,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Possibility of individual creating and optimizing to defined requirements,
- Versatile presence in future technologies – they are commonly used in mass storage devices, electric motors, advanced medical instruments, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Limited ability of producing nuts in the magnet and complex shapes - recommended is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface perfectly flat
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Product not for children
Neodymium magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Warning for heart patients
Patients with a heart stimulator have to keep an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Magnet fragility
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Compass and GPS
Remember: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Allergic reactions
Certain individuals experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause dermatitis. We recommend use safety gloves.
Combustion hazard
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Serious injuries
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Electronic hazard
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can permanently damage these devices and erase data from cards.
