Pros and cons of neodymium magnets.
Strengths
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under external field action,
- By using a reflective layer of gold, the element gains an proper look,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- In view of the ability of precise molding and adaptation to specialized requirements, neodymium magnets can be produced in a broad palette of forms and dimensions, which amplifies use scope,
- Versatile presence in innovative solutions – they serve a role in magnetic memories, motor assemblies, medical devices, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power 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 rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface free of scratches
- with direct contact (without paint)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – too thin plate does not close the flux, causing part of the power to be wasted into the air.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Metal Allergy
Some people experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in dermatitis. It is best to use protective gloves.
Phone sensors
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Serious injuries
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Cards and drives
Do not bring magnets near a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Maximum temperature
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Eye protection
Beware of splinters. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Implant safety
Warning for patients: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Immense force
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Dust explosion hazard
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
This is not a toy
These products are not intended for children. Swallowing multiple magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
