Pros as well as cons of rare earth magnets.
Strengths
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external magnetic fields,
- In other words, due to the metallic surface of silver, the element looks attractive,
- Neodymium magnets generate maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of flexible forming and adaptation to custom solutions, NdFeB magnets can be modeled in a wide range of shapes and sizes, which increases their versatility,
- Universal use in innovative solutions – they are utilized in HDD drives, motor assemblies, diagnostic systems, and complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a sheet made of mild steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- with a plane free of scratches
- with direct contact (without impurities)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Practical aspects of lifting capacity – 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.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of nominal force).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be escaped to the other side.
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Protect data
Equipment safety: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Physical harm
Big blocks can break fingers instantly. Never place your hand between two strong magnets.
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Swallowing risk
Always keep magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Avoid contact if allergic
Some people experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching might lead to an allergic reaction. It is best to wear safety gloves.
Immense force
Handle magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their force.
Fragile material
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Implant safety
Individuals with a pacemaker have to maintain an large gap from magnets. The magnetic field can stop the operation of the life-saving device.
Fire risk
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
