Advantages as well as disadvantages of rare earth magnets.
Benefits
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- A magnet with a metallic nickel surface is more attractive,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of detailed forming and adapting to specific conditions,
- Huge importance in innovative solutions – they are used in computer drives, electric motors, advanced medical instruments, and modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases 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 - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to 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
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- under conditions of no distance (metal-to-metal)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Permanent damage
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Choking Hazard
Only for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.
Keep away from electronics
A powerful magnetic field interferes with the functioning of compasses in smartphones and GPS navigation. Keep magnets near a device to prevent breaking the sensors.
Machining danger
Powder generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Pacemakers
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Finger safety
Big blocks can smash fingers instantly. Never place your hand between two strong magnets.
Magnets are brittle
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Metal Allergy
A percentage of the population suffer from a sensitization to nickel, which is the common plating for NdFeB magnets. Extended handling can result in a rash. We suggest use protective gloves.
Safe distance
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Caution required
Be careful. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.
