Pros and cons of rare earth magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They possess excellent resistance to magnetism drop when exposed to external magnetic sources,
- By covering with a decorative coating of silver, the element gains an aesthetic look,
- Magnetic induction on the working part of the magnet remains impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Thanks to versatility in constructing and the capacity to adapt to unusual requirements,
- Versatile presence in future technologies – they are used in data components, electric drive systems, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of creating threads in the magnet and complicated forms - preferred is casing - magnet mounting.
- Potential hazard 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 can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of mild steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with zero gap (without paint)
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Lifting capacity in real conditions – factors
- Gap (between the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted to the other side.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content decrease magnetic properties and holding force.
- Surface finish – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Safe handling of NdFeB magnets
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets will cause them cracking into small pieces.
Powerful field
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Fire risk
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Compass and GPS
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and GPS.
Physical harm
Risk of injury: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Life threat
Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the implant.
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for coated magnets.
Data carriers
Device Safety: Strong magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Thermal limits
Avoid heat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
This is not a toy
These products are not intended for children. Swallowing several magnets can lead to them attracting across intestines, which constitutes a critical condition and requires urgent medical intervention.
