Strengths as well as weaknesses of neodymium magnets.
Benefits
- Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- In other words, due to the reflective finish of nickel, the element looks attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of exact modeling and optimizing to individual conditions,
- Versatile presence in electronics industry – they serve a role in hard drives, brushless drives, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which enables their usage in miniature devices
Limitations
- They are fragile upon heavy 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
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complicated shapes - recommended is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum magnetic pulling force – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- with a cross-section no less than 10 mm
- with an ideally smooth touching surface
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Chemical composition of the base – mild steel gives the best results. Alloy steels lower magnetic properties and holding force.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Immense force
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Thermal limits
Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness appears, cease working with magnets and wear gloves.
Bone fractures
Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Protect data
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Threat to navigation
Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Do not give to children
Always keep magnets away from children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Fragile material
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Dust explosion hazard
Fire hazard: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
