Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They retain attractive force for nearly 10 years – the loss is just ~1% (based on simulations),
- They maintain their magnetic properties even under external field action,
- In other words, due to the glossy finish of silver, the element gains visual value,
- Neodymium magnets generate maximum magnetic induction on a small surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in constructing and the ability to adapt to unusual requirements,
- Huge importance in modern industrial fields – they find application in HDD drives, motor assemblies, medical equipment, also industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We recommend casing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of structural steel, effectively closing the magnetic flux
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by even structure
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- at temperature room level
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not accept the full field, causing part of the flux to be escaped into the air.
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface structure – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Pacemakers
Patients with a heart stimulator have to maintain an large gap from magnets. The magnetism can stop the operation of the implant.
Thermal limits
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Danger to the youngest
NdFeB magnets are not toys. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
Allergic reactions
Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, prevent direct skin contact and select encased magnets.
Do not drill into magnets
Mechanical processing of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Phone sensors
Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Respect the power
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Think ahead.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Protect data
Device Safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
