Pros as well as cons of rare earth magnets.
Benefits
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external interference,
- In other words, due to the shiny surface of gold, the element looks attractive,
- 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 modularity in constructing and the ability to customize to unusual requirements,
- Versatile presence in advanced technology sectors – they are commonly used in computer drives, drive modules, precision medical tools, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- with an ideally smooth touching surface
- with direct contact (without coatings)
- under axial force direction (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Life threat
Patients with a ICD have to maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
Warning for allergy sufferers
Certain individuals experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching can result in a rash. We suggest wear safety gloves.
Fire risk
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Data carriers
Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Shattering risk
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Crushing force
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Power loss in heat
Control the heat. Heating the magnet to high heat will ruin its properties and strength.
Caution required
Exercise caution. Neodymium magnets act from a distance and snap with huge force, often faster than you can move away.
Danger to the youngest
Always store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are fatal.
Phone sensors
A strong magnetic field interferes with the operation of compasses in phones and GPS navigation. Do not bring magnets near a device to prevent damaging the sensors.
