Strengths as well as weaknesses of neodymium magnets.
Benefits
- Their magnetic field is maintained, and after approximately ten years it drops only by ~1% (according to research),
- They have excellent resistance to magnetism drop due to external fields,
- A magnet with a shiny nickel surface has better aesthetics,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
- Thanks to versatility in designing and the capacity to adapt to unusual requirements,
- Universal use in innovative solutions – they find application in computer drives, electric motors, medical equipment, also modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- 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 and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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
- We suggest a housing - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- with a plane cleaned and smooth
- with direct contact (without paint)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Key elements affecting lifting force
- Clearance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be lost to the other side.
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Fire warning
Dust created during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Handling rules
Handle magnets consciously. Their huge power can surprise even professionals. Be vigilant and respect their force.
Metal Allergy
Certain individuals suffer from a contact allergy to nickel, which is the common plating for NdFeB magnets. Extended handling might lead to a rash. It is best to use protective gloves.
GPS Danger
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Fragile material
Despite metallic appearance, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Threat to electronics
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
No play value
NdFeB magnets are not toys. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a critical condition and necessitates immediate surgery.
Hand protection
Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
