Pros and cons of neodymium magnets.
Advantages
- Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under close interference source,
- By covering with a smooth layer of gold, the element presents an elegant look,
- They show high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of individual creating and adapting to individual needs,
- Universal use in innovative solutions – they are commonly used in HDD drives, motor assemblies, medical equipment, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these devices can disrupt the diagnostic process 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
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- with zero gap (without impurities)
- during pulling in a direction perpendicular to the plane
- at room temperature
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Do not underestimate power
Be careful. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.
Do not give to children
Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.
Do not drill into magnets
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
GPS and phone interference
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Protect data
Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Bodily injuries
Pinching hazard: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose versions in plastic housing.
Medical interference
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Demagnetization risk
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Magnets are brittle
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
