Strengths and weaknesses of rare earth magnets.
Strengths
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- In other words, due to the shiny layer of gold, the element is aesthetically pleasing,
- Magnetic induction on the surface of the magnet is very high,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the ability of flexible shaping and adaptation to unique solutions, magnetic components can be produced in a variety of shapes and sizes, which amplifies use scope,
- Huge importance in electronics industry – they are utilized in mass storage devices, drive modules, precision medical tools, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of creating threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished contact surface
- with direct contact (without coatings)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (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 available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Warnings
GPS Danger
A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Do not bring magnets close to a device to prevent breaking the sensors.
Crushing risk
Big blocks can crush fingers in a fraction of a second. Do not put your hand between two strong magnets.
No play value
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.
Shattering risk
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them cracking into shards.
Medical implants
Individuals with a ICD must maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Cards and drives
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Mechanical processing
Powder created during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent direct skin contact and choose versions in plastic housing.
Do not overheat magnets
Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Do not underestimate power
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
