Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They possess excellent resistance to magnetism drop as a result of external fields,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of precise creating and modifying to complex needs,
- Wide application in high-tech industry – they are commonly used in computer drives, electromotive mechanisms, medical equipment, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complicated forms in magnets, we propose using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane free of scratches
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be lost to the other side.
- Steel type – mild steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
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 holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Skin irritation risks
Studies show that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact and opt for encased magnets.
Threat to navigation
A strong magnetic field interferes with the functioning of compasses in phones and GPS navigation. Do not bring magnets near a device to avoid damaging the sensors.
Swallowing risk
Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Keep out of reach of children and animals.
Handling guide
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Physical harm
Large magnets can crush fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Dust is flammable
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them breaking into small pieces.
ICD Warning
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and pulling force.
