Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their strength is maintained, and after around ten years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- 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 detailed creating and modifying to complex applications,
- Wide application in innovative solutions – they are utilized in data components, electric drive systems, diagnostic systems, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength 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
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complex forms - recommended is cover - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness no less than 10 mm
- with an ground touching surface
- with direct contact (no impurities)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be wasted into the air.
- Chemical composition of the base – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Respect the power
Handle magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their force.
Power loss in heat
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Combustion hazard
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or choose coated magnets.
Pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Physical harm
Big blocks can smash fingers instantly. Do not put your hand betwixt two strong magnets.
Shattering risk
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Protect data
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Choking Hazard
Absolutely store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
Keep away from electronics
An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a device to prevent damaging the sensors.
