Advantages and disadvantages of rare earth magnets.
Benefits
- They do not lose power, even over around ten years – the reduction in lifting capacity is only ~1% (theoretically),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the glossy surface of gold, the element looks attractive,
- They feature high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping as well as adjusting to precise needs,
- Fundamental importance in high-tech industry – they find application in computer drives, drive modules, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also increases its resistance to damage
- 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 stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex shapes in magnets, we propose using a housing - magnetic mount.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a sheet made of mild steel, functioning as a magnetic yoke
- whose transverse dimension equals approx. 10 mm
- with an ground contact surface
- without the slightest insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When slipping, 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 passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Danger to pacemakers
Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.
Power loss in heat
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Electronic hazard
Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Dust is flammable
Powder produced during grinding of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Avoid contact if allergic
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands or choose versions in plastic housing.
Finger safety
Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
This is not a toy
Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Store away from kids and pets.
Do not underestimate power
Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Material brittleness
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Keep away from electronics
Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
