Pros as well as cons of rare earth magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively resist against demagnetization caused by external fields,
- Thanks to the reflective finish, the surface of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets are characterized by excellent magnetic induction on the active area,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the possibility of flexible shaping and customization to specialized projects, NdFeB magnets can be produced in a variety of geometric configurations, which amplifies use scope,
- Significant place in modern technologies – they are commonly used in magnetic memories, drive modules, advanced medical instruments, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in miniature devices
Cons
- 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
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in producing threads and complex forms in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of ideal adhesion (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped to the other side.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Danger to pacemakers
Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
Beware of splinters
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Dust explosion hazard
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Skin irritation risks
It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, avoid direct skin contact or choose versions in plastic housing.
Handling rules
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Do not overheat magnets
Keep cool. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
GPS and phone interference
Remember: rare earth magnets produce a field that disrupts precision electronics. Maintain a safe distance from your phone, device, and navigation systems.
Pinching danger
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Danger to the youngest
Neodymium magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.
