Pros and cons of neodymium magnets.
Pros
- They retain full power for around ten years – the loss is just ~1% (according to analyses),
- They are noted for resistance to demagnetization induced by presence of other magnetic fields,
- In other words, due to the metallic finish of gold, the element looks attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the option of precise molding and customization to custom needs, neodymium magnets can be modeled in a broad palette of geometric configurations, which amplifies use scope,
- Universal use in innovative solutions – they are utilized in data components, motor assemblies, diagnostic systems, also technologically advanced constructions.
- 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 protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a sheet made of mild steel, functioning as a magnetic yoke
- possessing a thickness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- with zero gap (without paint)
- during detachment in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Clearance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Danger to pacemakers
People with a heart stimulator must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Magnetic media
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
GPS and phone interference
GPS units and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Magnet fragility
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Fire warning
Powder created during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Caution required
Use magnets with awareness. Their immense force can surprise even professionals. Stay alert and respect their power.
Demagnetization risk
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Hand protection
Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
This is not a toy
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are fatal.
Metal Allergy
Some people experience a contact allergy to nickel, which is the standard coating for NdFeB magnets. Prolonged contact might lead to dermatitis. We strongly advise use protective gloves.
