Advantages and disadvantages of neodymium magnets.
Strengths
- They do not lose magnetism, even after nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny nickel surface has an effective appearance,
- Neodymium magnets ensure maximum magnetic induction on a their surface, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
- Thanks to the possibility of accurate molding and customization to specialized requirements, neodymium magnets can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Wide application in modern industrial fields – they are used in computer drives, electric drive systems, medical equipment, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We suggest cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose thickness equals approx. 10 mm
- characterized by even structure
- with direct contact (without paint)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted into the air.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Warnings
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Keep away from electronics
GPS units and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Protective goggles
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
Finger safety
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Keep away from children
Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
Cards and drives
Avoid bringing magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Safe operation
Use magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their force.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
