Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- Magnets effectively resist against loss of magnetization caused by external fields,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an elegant appearance,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Possibility of detailed machining as well as modifying to specific needs,
- Wide application in modern technologies – they serve a role in computer drives, electric drive systems, precision medical tools, and modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complex shapes - preferred is cover - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these devices are able to complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ground contact surface
- with total lack of distance (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature room level
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the power to be wasted into the air.
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Thermal limits
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Fragile material
Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Mechanical processing
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing force
Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Powerful field
Handle magnets with awareness. Their huge power can shock even professionals. Stay alert and respect their force.
Protect data
Device Safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Phone sensors
An intense magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to prevent damaging the sensors.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Choking Hazard
Neodymium magnets are not suitable for play. Eating several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Health Danger
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
