Strengths and weaknesses of rare earth magnets.
Benefits
- They do not lose power, even after approximately ten years – the decrease in strength is only ~1% (theoretically),
- They have excellent resistance to magnetism drop when exposed to external magnetic sources,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets create maximum magnetic induction on a small area, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Thanks to modularity in forming and the ability to adapt to complex applications,
- Significant place in electronics industry – they find application in magnetic memories, electric drive systems, medical equipment, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic flux
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in stable room temperature
Determinants of lifting force in real conditions
- Gap (between the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels reduce magnetic properties and holding force.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Threat to navigation
Note: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, device, and GPS.
Permanent damage
Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.
Immense force
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Protect data
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Health Danger
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Finger safety
Large magnets can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Adults only
These products are not toys. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a critical condition and requires immediate surgery.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
