Pros and cons of neodymium magnets.
Strengths
- They retain magnetic properties for nearly ten years – the loss is just ~1% (according to analyses),
- They are noted for resistance to demagnetization induced by external disturbances,
- Thanks to the glossy finish, the surface of Ni-Cu-Ni, gold, or silver gives an modern appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a key feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in constructing and the ability to modify to unusual requirements,
- Significant place in high-tech industry – they find application in HDD drives, electric motors, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of creating threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys attracts identically. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with neodymium magnets
Warning for heart patients
Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.
Fragile material
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Skin irritation risks
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose versions in plastic housing.
Powerful field
Be careful. Rare earth magnets act from a long distance and snap with massive power, often quicker than you can react.
Crushing risk
Big blocks can crush fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Adults only
Always keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are very dangerous.
Heat warning
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Protect data
Avoid bringing magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Machining danger
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
