Advantages and disadvantages of neodymium magnets.
Strengths
- They retain full power for almost ten years – the drop is just ~1% (based on simulations),
- They maintain their magnetic properties even under strong external field,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
- 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...
- Considering the ability of flexible forming and customization to individualized solutions, NdFeB magnets can be created in a wide range of shapes and sizes, which makes them more universal,
- Wide application in advanced technology sectors – they serve a role in data components, drive modules, medical devices, as well as multitasking production systems.
- 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 strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complex forms in magnets, we propose using casing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these magnets can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane perfectly flat
- without any air gap between the magnet and steel
- under perpendicular force direction (90-degree angle)
- in stable room temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Fire risk
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Physical harm
Big blocks can smash fingers instantly. Do not put your hand between two attracting surfaces.
Power loss in heat
Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Electronic devices
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them cracking into small pieces.
Pacemakers
People with a pacemaker must keep an absolute distance from magnets. The magnetic field can stop the operation of the life-saving device.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for coated magnets.
Precision electronics
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Handling guide
Handle magnets with awareness. Their powerful strength can shock even professionals. Stay alert and respect their power.
Adults only
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
