Strengths and weaknesses of neodymium magnets.
Benefits
- Their strength is maintained, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets remain highly resistant to demagnetization caused by external field sources,
- In other words, due to the reflective finish of silver, the element gains a professional look,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- 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 detailed machining and adapting to complex needs,
- Wide application in innovative solutions – they find application in magnetic memories, drive modules, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complicated forms - recommended is casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these devices can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a plate made of high-permeability steel, acting as a ideal flux conductor
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Magnetic media
Powerful magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Crushing force
Mind your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Magnets are brittle
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Do not underestimate power
Be careful. Rare earth magnets act from a distance and connect with huge force, often quicker than you can move away.
GPS and phone interference
Note: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation happens, immediately stop working with magnets and wear gloves.
Implant safety
Patients with a ICD have to maintain an large gap from magnets. The magnetic field can interfere with the operation of the implant.
No play value
Always keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.
