Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even during nearly ten years – the reduction in strength is only ~1% (based on measurements),
- They are resistant to demagnetization induced by external field influence,
- By applying a lustrous layer of silver, the element acquires an proper look,
- Magnets are characterized by very high magnetic induction on the working surface,
- 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...
- Thanks to freedom in shaping and the ability to modify to complex applications,
- Wide application in future technologies – they are commonly used in computer drives, electromotive mechanisms, diagnostic systems, and complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complex shapes - preferred is cover - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these devices can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- using a plate made of high-permeability steel, functioning as a magnetic yoke
- with a cross-section of at least 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Air gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick plate causes magnetic saturation, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Implant safety
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Adults only
These products are not intended for children. Accidental ingestion of several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
Dust is flammable
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Bone fractures
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Permanent damage
Do not overheat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Keep away from computers
Do not bring magnets close to a purse, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Safe operation
Handle magnets with awareness. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.
Precision electronics
Note: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Metal Allergy
Some people have a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. It is best to wear protective gloves.
