Pros and cons of rare earth magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by highly resistant to loss of magnetic properties caused by external magnetic fields,
- By applying a smooth layer of gold, the element acquires an modern look,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Considering the possibility of precise molding and customization to individualized needs, magnetic components can be manufactured in a variety of forms and dimensions, which amplifies use scope,
- Universal use in electronics industry – they find application in data components, electric motors, diagnostic systems, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a block made of structural steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Fragile material
NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into small pieces.
Swallowing risk
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
Pacemakers
Individuals with a pacemaker should maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Allergic reactions
Certain individuals experience a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause an allergic reaction. We suggest use safety gloves.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
GPS Danger
GPS units and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Magnetic media
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Pinching danger
Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Heat warning
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Safe operation
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
