Advantages and disadvantages of neodymium magnets.
Strengths
- Their magnetic field is durable, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets effectively resist against demagnetization caused by external fields,
- A magnet with a metallic silver surface has an effective appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Due to the potential of flexible shaping and customization to individualized projects, magnetic components can be produced in a broad palette of geometric configurations, which expands the range of possible applications,
- Universal use in advanced technology sectors – they serve a role in computer drives, electric drive systems, diagnostic systems, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these products are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- using a plate made of low-carbon steel, acting as a circuit closing element
- possessing a thickness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
GPS and phone interference
Note: neodymium magnets generate a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.
Warning for heart patients
Individuals with a heart stimulator must keep an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Data carriers
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Eye protection
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them shattering into shards.
Fire warning
Powder generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
Handling guide
Handle magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their force.
Allergic reactions
A percentage of the population have a sensitization to Ni, which is the common plating for neodymium magnets. Extended handling can result in skin redness. We suggest wear protective gloves.
Serious injuries
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Heat sensitivity
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Do not give to children
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.
