Pros and cons of neodymium magnets.
Strengths
- They do not lose magnetism, even over approximately 10 years – the decrease in strength is only ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- In other words, due to the smooth surface of gold, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the ability of free forming and adaptation to specialized solutions, magnetic components can be manufactured in a broad palette of geometric configurations, which makes them more universal,
- Huge importance in modern technologies – they find application in hard drives, electric drive systems, medical devices, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks upon strong impacts, we recommend 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 strength. 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section minimum 10 mm
- with an ground contact surface
- without the slightest insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Distance (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Material composition – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Safe distance
Device Safety: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
Keep away from children
These products are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
Beware of splinters
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Nickel coating and allergies
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, cease handling magnets and wear gloves.
Machining danger
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Immense force
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Magnetic interference
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Hand protection
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
