Pros as well as cons of rare earth magnets.
Advantages
- They retain attractive force for around ten years – the drop is just ~1% (based on simulations),
- Magnets very well defend themselves against demagnetization caused by foreign field sources,
- By covering with a reflective layer of nickel, the element has an aesthetic look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Neodymium magnets are characterized by extremely 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 the possibility of accurate shaping and customization to custom needs, magnetic components can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
- Versatile presence in electronics industry – they are utilized in mass storage devices, electric motors, medical equipment, as well as complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets experience a drop in strength. 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a sheet made of low-carbon steel, functioning as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- with total lack of distance (without coatings)
- during pulling in a direction vertical to the mounting surface
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
GPS and phone interference
An intense magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets near a device to prevent damaging the sensors.
Handling guide
Handle with care. Rare earth magnets act from a long distance and snap with massive power, often faster than you can move away.
Fire risk
Powder produced during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Pacemakers
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
This is not a toy
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, cease handling magnets and use protective gear.
Data carriers
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Permanent damage
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Serious injuries
Large magnets can smash fingers instantly. Under no circumstances put your hand between two attracting surfaces.
