Other offers
Strengths and weaknesses of neodymium magnets.
Pros
- They retain attractive force for almost 10 years – the loss is just ~1% (according to analyses),
- They feature excellent resistance to weakening of magnetic properties as a result of external fields,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets possess exceptionally strong magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in constructing and the ability to adapt to client solutions,
- Wide application in future technologies – they are commonly used in hard drives, electromotive mechanisms, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in miniature devices
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- whose thickness is min. 10 mm
- characterized by even structure
- with total lack of distance (no coatings)
- for force applied at a right angle (in the magnet axis)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Clearance – the presence of foreign body (paint, tape, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted to the other side.
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic properties and holding force.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Skin irritation risks
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact and select encased magnets.
Pinching danger
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Mechanical processing
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Life threat
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Fragile material
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Cards and drives
Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Precision electronics
A powerful magnetic field disrupts the operation of magnetometers in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
This is not a toy
Absolutely keep magnets away from children. Ingestion danger is high, and the consequences of magnets connecting inside the body are tragic.
Power loss in heat
Do not overheat. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Handling rules
Be careful. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
