Strengths as well as weaknesses of rare earth magnets.
Benefits
- They have stable power, and over nearly 10 years their performance 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 metallic layer of silver, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Thanks to freedom in constructing and the ability to modify to complex applications,
- Huge importance in future technologies – they are utilized in data components, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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 creating nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum magnetic pulling force – what affects it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Allergic reactions
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Compass and GPS
A strong magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Beware of splinters
Despite the nickel coating, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Hand protection
Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Danger to the youngest
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Machining danger
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Data carriers
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Safe operation
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
ICD Warning
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
