Strengths as well as weaknesses of neodymium magnets.
Benefits
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets remain highly resistant to loss of magnetic properties caused by external interference,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are characterized by maximum magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely 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...
- Considering the ability of precise molding and customization to individualized requirements, magnetic components can be produced in a wide range of shapes and sizes, which expands the range of possible applications,
- Huge importance in innovative solutions – they serve a role in data components, electric drive systems, advanced medical instruments, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong 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 decrease 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we recommend using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to avoid saturation
- with an ground touching surface
- without any insulating layer between the magnet and steel
- during pulling in a direction vertical to the plane
- in stable room temperature
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, 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 passes through the material instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy steels decrease magnetic permeability and holding force.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Respect the power
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
This is not a toy
Adult use only. Tiny parts can be swallowed, causing intestinal necrosis. Store away from kids and pets.
Dust is flammable
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Pinching danger
Big blocks can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.
GPS Danger
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Power loss in heat
Monitor thermal conditions. Exposing the magnet to high heat will destroy its magnetic structure and strength.
Pacemakers
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Material brittleness
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Allergic reactions
Some people suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in dermatitis. We suggest wear protective gloves.
