Strengths as well as weaknesses of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They are extremely resistant to demagnetization induced by external field influence,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the potential of accurate forming and customization to specialized projects, NdFeB magnets can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Huge importance in modern technologies – they are used in HDD drives, electromotive mechanisms, advanced medical instruments, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend casing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a sheet made of high-permeability steel, serving as a circuit closing element
- with a thickness of at least 10 mm
- with a plane perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Electronic devices
Do not bring magnets near a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.
Respect the power
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Medical interference
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into small pieces.
Allergy Warning
Medical facts indicate that nickel (standard magnet coating) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.
Do not overheat magnets
Watch the temperature. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Danger to the youngest
Only for adults. Tiny parts can be swallowed, leading to serious injuries. Store away from children and animals.
Bodily injuries
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Machining danger
Drilling and cutting of NdFeB material poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
