Pros and cons of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under external field action,
- A magnet with a smooth silver surface has better aesthetics,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Due to the potential of free molding and customization to individualized needs, NdFeB magnets can be created in a variety of geometric configurations, which makes them more universal,
- Wide application in innovative solutions – they are used in mass storage devices, brushless drives, medical equipment, and modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's 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. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness no less than 10 mm
- with an ground touching surface
- with zero gap (without paint)
- under vertical force vector (90-degree angle)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the load capacity.
Safety rules for work with neodymium magnets
Bodily injuries
Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Protective goggles
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Compass and GPS
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Operating temperature
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Sensitization to coating
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands and choose versions in plastic housing.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Medical interference
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
This is not a toy
Neodymium magnets are not intended for children. Eating several magnets can lead to them attracting across intestines, which constitutes a direct threat to life and requires urgent medical intervention.
Conscious usage
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Dust is flammable
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
