Strengths and weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They retain their magnetic properties even under close interference source,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the ability to adapt to unusual requirements,
- Huge importance in electronics industry – they are commonly used in data components, brushless drives, precision medical tools, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Limitations
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose strength 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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at ambient temperature room level
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be escaped to the other side.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Bodily injuries
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Risk of cracking
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Heat warning
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and strength.
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid direct skin contact or select coated magnets.
Danger to the youngest
Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Store away from children and animals.
Medical implants
Patients with a pacemaker must keep an absolute distance from magnets. The magnetic field can disrupt the operation of the life-saving device.
Precision electronics
A strong magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Keep magnets close to a smartphone to avoid breaking the sensors.
Protect data
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, mechanical watches).
Combustion hazard
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Conscious usage
Handle with care. Neodymium magnets attract from a distance and connect with massive power, often quicker than you can move away.
