Strengths and weaknesses of neodymium magnets.
Strengths
- They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
- They have excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a shiny silver surface is more attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to the ability of accurate molding and adaptation to unique needs, magnetic components can be created in a wide range of shapes and sizes, which makes them more universal,
- Universal use in modern industrial fields – they find application in HDD drives, brushless drives, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated shapes in magnets, we propose using cover - magnetic mount.
- Health risk resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- using a base made of low-carbon steel, serving as a circuit closing element
- with a cross-section of at least 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped into the air.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature – temperature increase results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Caution required
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Protective goggles
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Operating temperature
Do not overheat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Impact on smartphones
A powerful magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to prevent damaging the sensors.
Protect data
Do not bring magnets near a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Nickel coating and allergies
Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact and select versions in plastic housing.
Keep away from children
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from kids and pets.
ICD Warning
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Mechanical processing
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Bone fractures
Large magnets can break fingers instantly. Never place your hand betwixt two strong magnets.
