Pros and cons of rare earth magnets.
Pros
- Their power is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- In other words, due to the reflective finish of nickel, the element gains visual value,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual modeling and optimizing to defined requirements,
- Huge importance in modern technologies – they are commonly used in HDD drives, electric motors, medical equipment, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Highest magnetic holding force – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- with zero gap (no impurities)
- under perpendicular force direction (90-degree angle)
- at room temperature
What influences lifting capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Cards and drives
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Sensitization to coating
Studies show that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, prevent direct skin contact or opt for coated magnets.
Keep away from electronics
A powerful magnetic field disrupts the operation of compasses in phones and navigation systems. Keep magnets close to a smartphone to prevent damaging the sensors.
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Flammability
Powder created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Permanent damage
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
This is not a toy
Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Serious injuries
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Warning for heart patients
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
