Pros as well as cons of rare earth magnets.
Benefits
- They do not lose magnetism, even over approximately 10 years – the reduction in lifting capacity is only ~1% (according to tests),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a shiny silver surface has an effective appearance,
- Neodymium magnets deliver maximum magnetic induction on a their 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...
- In view of the potential of precise shaping and adaptation to specialized solutions, magnetic components can be manufactured in a variety of forms and dimensions, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they serve a role in data components, electric drive systems, precision medical tools, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Base massiveness – too thin plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Chemical composition of the base – mild steel gives the best results. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Mechanical processing
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Protective goggles
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Physical harm
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Maximum temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.
Keep away from computers
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Keep away from electronics
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Safe operation
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Adults only
Neodymium magnets are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
Medical interference
People with a pacemaker must keep an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
