Pros and cons of neodymium magnets.
Pros
- They do not lose strength, even during around ten years – the reduction in strength is only ~1% (based on measurements),
- Neodymium magnets are distinguished by exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- Possibility of custom modeling as well as adapting to defined needs,
- Wide application in advanced technology sectors – they serve a role in data components, drive modules, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in creating threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a block made of structural steel, optimally conducting the magnetic field
- with a thickness of at least 10 mm
- with an polished touching surface
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the plane
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.
Pacemakers
Patients with a ICD should keep an absolute distance from magnets. The magnetic field can stop the operation of the implant.
Danger to the youngest
Strictly store magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
Magnets are brittle
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Precision electronics
A powerful magnetic field interferes with the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to prevent damaging the sensors.
Magnetic media
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Machining danger
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Handling rules
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Finger safety
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
