Other products
Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- They feature high magnetic induction at the operating surface, which increases their power,
- 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 flexible shaping and customization to specialized needs, neodymium magnets can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Huge importance in future technologies – they are utilized in HDD drives, electric motors, precision medical tools, as well as industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power 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
- 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
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- with an polished touching surface
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Plate material – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, cease handling magnets and use protective gear.
Pacemakers
Patients with a ICD should maintain an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Mechanical processing
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Bone fractures
Large magnets can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Handling guide
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can move away.
Safe distance
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
No play value
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Keep out of reach of children and animals.
Thermal limits
Keep cool. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Magnetic interference
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
