Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose magnetism, even after around 10 years – the drop in strength is only ~1% (based on measurements),
- They do not lose their magnetic properties even under external field action,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets have huge magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of detailed creating and adapting to individual applications,
- Huge importance in high-tech industry – they serve a role in HDD drives, electric drive systems, medical equipment, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power 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
- 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 secure oxidation and corrosion.
- We recommend a housing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these products can complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- on a block made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- with direct contact (no paint)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Clearance – the presence of any layer (paint, dirt, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of nominal force).
- Steel thickness – too thin plate does not close the flux, causing part of the power to be wasted into the air.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Do not give to children
Neodymium magnets are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Machining danger
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Crushing risk
Pinching hazard: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and wear gloves.
Handling guide
Before use, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Compass and GPS
Note: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
Cards and drives
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Heat warning
Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and strength.
Danger to pacemakers
People with a ICD have to keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets leads to them breaking into small pieces.
