Strengths and weaknesses of rare earth magnets.
Advantages
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- Neodymium magnets are distinguished by extremely resistant to demagnetization caused by magnetic disturbances,
- A magnet with a smooth silver surface looks better,
- Magnets are distinguished by impressive magnetic induction on the surface,
- Neodymium magnets are characterized by very 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 freedom in constructing and the ability to customize to unusual requirements,
- Significant place in advanced technology sectors – they find application in data components, electric drive systems, diagnostic systems, as well as modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- 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.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing threads in the magnet and complicated forms - preferred is cover - magnet mounting.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Furthermore, tiny parts of these devices can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- using a sheet made of low-carbon steel, acting as a magnetic yoke
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface perfectly flat
- with zero gap (no paint)
- under axial force direction (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted to the other side.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Combustion hazard
Powder created during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Keep away from children
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
Operating temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Danger to pacemakers
People with a pacemaker must keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Do not underestimate power
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can react.
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a common allergen. For allergy sufferers, refrain from direct skin contact and select versions in plastic housing.
Shattering risk
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
GPS Danger
Note: neodymium magnets produce a field that interferes with precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Threat to electronics
Data protection: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Hand protection
Big blocks can break fingers instantly. Never place your hand between two attracting surfaces.
