Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose strength, even during nearly ten years – the reduction in power is only ~1% (according to tests),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- By applying a reflective layer of nickel, the element has an aesthetic look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual shaping as well as optimizing to defined conditions,
- Key role in high-tech industry – they are utilized in HDD drives, electric drive systems, diagnostic systems, also multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Health risk to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis 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
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of mild steel, functioning as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the load capacity.
H&S for magnets
GPS Danger
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Do not underestimate power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
This is not a toy
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Store out of reach of children and animals.
Power loss in heat
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Beware of splinters
NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them breaking into small pieces.
Flammability
Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Medical implants
People with a ICD have to maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Pinching danger
Big blocks can break fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
Allergy Warning
A percentage of the population experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Frequent touching can result in a rash. We strongly advise wear safety gloves.
