Strengths as well as weaknesses of rare earth magnets.
Benefits
- Their strength remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets perfectly defend themselves against loss of magnetization caused by foreign field sources,
- A magnet with a shiny silver surface looks better,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in constructing and the ability to modify to specific needs,
- Key role in modern technologies – they are used in computer drives, electromotive mechanisms, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- 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 contributes to it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- whose thickness is min. 10 mm
- characterized by smoothness
- with total lack of distance (no paint)
- during detachment in a direction perpendicular to the plane
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Protect data
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
ICD Warning
Individuals with a pacemaker have to keep an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Demagnetization risk
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Finger safety
Large magnets can crush fingers instantly. Do not put your hand betwixt two strong magnets.
Product not for children
Always store magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are fatal.
GPS Danger
An intense magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
Fire risk
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Metal Allergy
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands or opt for encased magnets.
Shattering risk
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
