Pros as well as cons of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They are resistant to demagnetization induced by external disturbances,
- A magnet with a smooth silver surface looks better,
- Neodymium magnets generate maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in constructing and the capacity to modify to individual projects,
- Fundamental importance in innovative solutions – they find application in magnetic memories, electric motors, medical devices, and modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating nuts in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- whose thickness reaches at least 10 mm
- with an polished contact surface
- with zero gap (without paint)
- during detachment in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content weaken the attraction effect.
- Smoothness – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Adults only
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Combustion hazard
Machining of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Health Danger
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Safe distance
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Threat to navigation
Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Physical harm
Danger of trauma: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Shattering risk
Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Powerful field
Use magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and respect their force.
Nickel coating and allergies
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or choose versions in plastic housing.
