Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain magnetic properties for almost 10 years – the loss is just ~1% (based on simulations),
- Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by external interference,
- By applying a shiny layer of nickel, the element acquires an aesthetic look,
- Neodymium magnets create maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- 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...
- Thanks to versatility in constructing and the capacity to customize to individual projects,
- Universal use in electronics industry – they find application in magnetic memories, brushless drives, advanced medical instruments, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- 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, in case of application outdoors
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using cover - magnetic mechanism.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a base made of mild steel, serving as a circuit closing element
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- under axial force vector (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
Handling guide
Handle with care. Neodymium magnets attract from a long distance and connect with huge force, often quicker than you can react.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Fragile material
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
GPS and phone interference
A powerful magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Implant safety
Individuals with a pacemaker have to maintain an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
No play value
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Store away from kids and pets.
Fire warning
Dust created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Permanent damage
Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Serious injuries
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
