Pros as well as cons of rare earth magnets.
Advantages
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- They maintain their magnetic properties even under close interference source,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate modeling and modifying to atypical conditions,
- Significant place in electronics industry – they serve a role in data components, electromotive mechanisms, medical devices, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Highest magnetic holding force – what affects it?
- using a plate made of low-carbon steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- with an ground touching surface
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not close the flux, causing part of the flux to be lost to the other side.
- Steel type – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
This is not a toy
These products are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Metal Allergy
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact and choose encased magnets.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
GPS and phone interference
Remember: rare earth magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Caution required
Handle magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.
Medical interference
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Hand protection
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Safe distance
Do not bring magnets near a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Dust explosion hazard
Fire hazard: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
