Pros as well as cons of rare earth magnets.
Benefits
- They do not lose power, even over around ten years – the reduction in strength is only ~1% (theoretically),
- They feature excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- In other words, due to the shiny layer of nickel, the element gains visual value,
- Neodymium magnets generate maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Thanks to freedom in constructing and the ability to modify to complex applications,
- Wide application in modern technologies – they serve a role in hard drives, drive modules, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their 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, as well as 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend casing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Magnetic strength at its maximum – what affects it?
- with the contact of a yoke made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an polished contact surface
- without any insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Air gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Plate material – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Machining danger
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
No play value
Neodymium magnets are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.
Thermal limits
Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease working with magnets and use protective gear.
Finger safety
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
Eye protection
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Keep away from electronics
An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.
Caution required
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and respect their force.
Implant safety
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Keep away from computers
Powerful magnetic fields can destroy records on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
