Other offers
Pros as well as cons of neodymium magnets.
Strengths
- They retain full power for almost 10 years – the loss is just ~1% (based on simulations),
- They are extremely resistant to demagnetization induced by external disturbances,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working part of the magnet is maximum,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the ability of precise forming and adaptation to specialized projects, NdFeB magnets can be produced in a wide range of shapes and sizes, which increases their versatility,
- Universal use in advanced technology sectors – they are commonly used in computer drives, brushless drives, medical devices, as well as complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- with zero gap (no impurities)
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature room level
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Cast iron may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Magnet fragility
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Finger safety
Large magnets can break fingers instantly. Do not place your hand between two strong magnets.
Keep away from electronics
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Warning for heart patients
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Product not for children
Adult use only. Small elements can be swallowed, leading to serious injuries. Store away from children and animals.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
Powerful field
Handle with care. Neodymium magnets act from a distance and snap with massive power, often quicker than you can react.
Machining danger
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Keep away from computers
Do not bring magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
