Pros and cons of neodymium magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the glossy finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of accurate forming and adapting to complex needs,
- Huge importance in modern industrial fields – they are used in computer drives, drive modules, medical devices, and multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. 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
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex shapes in magnets, we propose using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Magnetic strength at its maximum – what it depends on?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ground contact surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Medical interference
People with a ICD have to maintain an large gap from magnets. The magnetism can interfere with the functioning of the implant.
Beware of splinters
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
No play value
Strictly keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are fatal.
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Keep away from computers
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Powerful field
Be careful. Neodymium magnets attract from a distance and snap with huge force, often faster than you can move away.
Pinching danger
Large magnets can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Magnetic interference
A strong magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Metal Allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and use protective gear.
