Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under external field action,
- By covering with a reflective coating of gold, the element presents an elegant look,
- Neodymium magnets achieve maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Considering the possibility of accurate forming and customization to unique projects, NdFeB magnets can be produced in a wide range of shapes and sizes, which makes them more universal,
- Wide application in modern industrial fields – they serve a role in data components, brushless drives, medical equipment, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Keep away from electronics
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, cease handling magnets and use protective gear.
Serious injuries
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Do not overheat magnets
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Fire risk
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Keep away from children
These products are not toys. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a direct threat to life and requires immediate surgery.
Keep away from computers
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Magnets are brittle
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Powerful field
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
