Strengths as well as weaknesses of neodymium magnets.
Advantages
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic layer of silver, the element looks attractive,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the capacity to adapt to specific needs,
- Fundamental importance in future technologies – they are utilized in magnetic memories, brushless drives, precision medical tools, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience 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
- We recommend cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- with a cross-section minimum 10 mm
- with an polished contact surface
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Distance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Fire warning
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Magnetic media
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
Life threat
Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the life-saving device.
Physical harm
Big blocks can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Do not overheat magnets
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Shattering risk
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them shattering into shards.
Threat to navigation
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
Keep away from children
Only for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from children and animals.
Caution required
Handle magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
Allergy Warning
Some people experience a sensitization to Ni, which is the common plating for NdFeB magnets. Extended handling can result in a rash. We suggest use protective gloves.
