Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain attractive force for around ten years – the loss is just ~1% (based on simulations),
- They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets exhibit impressive magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the option of accurate forming and customization to individualized solutions, neodymium magnets can be manufactured in a wide range of geometric configurations, which makes them more universal,
- Huge importance in innovative solutions – they serve a role in mass storage devices, electromotive mechanisms, medical devices, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects 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 power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- whose transverse dimension reaches at least 10 mm
- with a plane perfectly flat
- under conditions of no distance (metal-to-metal)
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – high temperature weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Material brittleness
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Adults only
These products are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Dust explosion hazard
Powder generated during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Power loss in heat
Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Respect the power
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
GPS and phone interference
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.
Pinching danger
Large magnets can smash fingers in a fraction of a second. Do not put your hand between two strong magnets.
Metal Allergy
A percentage of the population suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We recommend wear protective gloves.
Safe distance
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
