Magnetic properties of material
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Advantages and disadvantages of neodymium magnets.
Apart from their strong magnetic energy, neodymium magnets have these key benefits:
- They do not lose strength, even over approximately 10 years – the drop in power is only ~1% (based on measurements),
- Magnets perfectly resist against loss of magnetization caused by external fields,
- In other words, due to the reflective surface of gold, the element gains visual value,
- Magnetic induction on the top side of the magnet turns out to be strong,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to the potential of precise forming and customization to custom projects, NdFeB magnets can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in high-tech industry – they find application in HDD drives, motor assemblies, diagnostic systems, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages of neodymium magnets:
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises 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 and 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, in case of application outdoors
- We recommend a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Maximum lifting capacity of the magnet – what it depends on?
Breakaway force was determined for ideal contact conditions, taking into account:
- with the contact of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- characterized by even structure
- without any air gap between the magnet and steel
- under vertical force vector (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
Real force is influenced by specific conditions, mainly (from priority):
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
* Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap {between} the magnet’s surface and the plate decreases the holding force.
Warnings
Do not drill into magnets
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Immense force
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Swallowing risk
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are fatal.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Precision electronics
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Nickel allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.
Serious injuries
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Use thick gloves.
ICD Warning
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Protect data
Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Shattering risk
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
