Strengths as well as weaknesses of rare earth magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly defend themselves against demagnetization caused by external fields,
- In other words, due to the reflective layer of silver, the element looks attractive,
- Magnets are distinguished by very high magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the capacity to adapt to individual projects,
- Key role in advanced technology sectors – they are utilized in data components, electric drive systems, medical devices, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic holder.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these products can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- whose thickness is min. 10 mm
- with a surface perfectly flat
- under conditions of no distance (metal-to-metal)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Keep away from computers
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Physical harm
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Demagnetization risk
Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Flammability
Dust created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Material brittleness
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
ICD Warning
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Impact on smartphones
A strong magnetic field interferes with the operation of magnetometers in phones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
Allergic reactions
A percentage of the population have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We suggest wear safety gloves.
No play value
Adult use only. Small elements pose a choking risk, causing severe trauma. Keep away from children and animals.
