Strengths as well as weaknesses of rare earth magnets.
Advantages
- They retain magnetic properties for around ten years – the drop is just ~1% (based on simulations),
- They have excellent resistance to magnetism drop as a result of opposing magnetic fields,
- A magnet with a smooth gold surface has an effective appearance,
- Magnetic induction on the top side of the magnet remains impressive,
- 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 custom shaping and adapting to concrete requirements,
- Wide application in modern technologies – they are commonly used in data components, electric motors, medical devices, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited possibility of producing nuts in the magnet and complex shapes - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- with zero gap (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate does not close the flux, causing part of the power to be wasted into the air.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Cards and drives
Avoid bringing magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Physical harm
Large magnets can crush fingers instantly. Do not place your hand betwixt two strong magnets.
Danger to the youngest
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.
Fragile material
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Compass and GPS
Navigation devices and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Medical interference
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Metal Allergy
Some people suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Extended handling may cause a rash. We recommend wear protective gloves.
Fire warning
Powder created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Do not overheat magnets
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Immense force
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
