Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain magnetic properties for around ten years – the drop is just ~1% (in theory),
- They retain their magnetic properties even under strong external field,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the option of accurate shaping and adaptation to individualized projects, neodymium magnets can be modeled in a wide range of forms and dimensions, which makes them more universal,
- Key role in modern industrial fields – they are commonly used in mass storage devices, brushless drives, medical devices, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a cross-section minimum 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
What influences lifting capacity in practice
- Clearance – existence of any layer (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 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 steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Compass and GPS
A strong magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Eye protection
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Warning for allergy sufferers
Some people have a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to a rash. It is best to wear safety gloves.
Physical harm
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Adults only
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Medical implants
People with a pacemaker must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Electronic devices
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Heat sensitivity
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Safe operation
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
