Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for almost 10 years – the drop is just ~1% (based on simulations),
- Magnets very well defend themselves against loss of magnetization caused by ambient magnetic noise,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in shaping and the capacity to customize to unusual requirements,
- Huge importance in electronics industry – they are used in HDD drives, electric motors, advanced medical instruments, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex forms in magnets, we propose using cover - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- on a block made of mild steel, optimally conducting the magnetic flux
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- with total lack of distance (no impurities)
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be lost into the air.
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Threat to electronics
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Handling guide
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their power.
Material brittleness
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Maximum temperature
Monitor thermal conditions. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Crushing force
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
Swallowing risk
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep away from kids and pets.
Pacemakers
Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
GPS Danger
A powerful magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
