Pros as well as cons of neodymium magnets.
Advantages
- They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- Magnets very well protect themselves against loss of magnetization caused by external fields,
- A magnet with a metallic nickel surface looks better,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- 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...
- Thanks to freedom in designing and the ability to adapt to unusual requirements,
- Huge importance in advanced technology sectors – they are used in data components, electric motors, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complicated shapes - recommended is cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Highest magnetic holding force – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ground contact surface
- without any air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
H&S for magnets
Heat warning
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Magnets are brittle
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Threat to electronics
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Stay away of at least 10 cm.
Handling rules
Exercise caution. Rare earth magnets act from a distance and connect with huge force, often faster than you can react.
GPS and phone interference
Be aware: rare earth magnets generate a field that interferes with precision electronics. Maintain a safe distance from your phone, device, and GPS.
Fire warning
Dust generated during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Crushing risk
Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Medical implants
People with a pacemaker have to maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
This is not a toy
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from children and animals.
