Pros as well as cons of rare earth magnets.
Advantages
- Their power is durable, and after approximately 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by exceptionally resistant to demagnetization caused by magnetic disturbances,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of detailed forming as well as adapting to atypical requirements,
- Fundamental importance in high-tech industry – they are used in magnetic memories, electromotive mechanisms, diagnostic systems, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease their force 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
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex shapes - preferred is casing - magnet mounting.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of low-carbon steel, acting as a magnetic yoke
- with a cross-section no less than 10 mm
- with an ideally smooth touching surface
- without any insulating layer between the magnet and steel
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (rust, dirt, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin steel does not accept the full field, causing part of the power to be escaped into the air.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
H&S for magnets
Protect data
Very strong magnetic fields can destroy records on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Crushing force
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
GPS and phone interference
A powerful magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Product not for children
Neodymium magnets are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
Powerful field
Be careful. Neodymium magnets act from a distance and snap with massive power, often faster than you can react.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Skin irritation risks
It is widely known that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or opt for encased magnets.
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Flammability
Powder generated during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
