Pros and cons of rare earth magnets.
In addition to their long-term stability, neodymium magnets provide the following advantages:
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They are noted for resistance to demagnetization induced by external magnetic fields,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which increases force concentration,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- In view of the potential of accurate molding and customization to specialized projects, neodymium magnets can be produced in a broad palette of forms and dimensions, which expands the range of possible applications,
- Versatile presence in modern industrial fields – they are used in computer drives, electric drive systems, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages of neodymium magnets:
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength 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 suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Maximum magnetic pulling force – what contributes to it?
The declared magnet strength refers to the limit force, obtained under optimal environment, specifically:
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- under conditions of no distance (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
Please note that the working load may be lower influenced by the following factors, starting with the most relevant:
- Distance – the presence of foreign body (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted into the air.
- Material composition – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
* Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance {between} the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Caution required
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
Electronic devices
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can destroy these devices and erase data from cards.
Machining danger
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Implant safety
For implant holders: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Adults only
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
Impact on smartphones
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
Bodily injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Avoid contact if allergic
Some people experience a contact allergy to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to an allergic reaction. We recommend use protective gloves.
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Permanent damage
Avoid heat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
