Other proposals
Strengths and weaknesses of rare earth magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the glossy layer of nickel, the element looks attractive,
- Magnetic induction on the working layer of the magnet is strong,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in designing and the capacity to adapt to complex applications,
- Fundamental importance in high-tech industry – they are utilized in HDD drives, electric motors, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in compact constructions
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a sheet made of special test steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Distance (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with neodymium magnets
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Do not drill into magnets
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Bone fractures
Large magnets can smash fingers instantly. Do not put your hand betwixt two strong magnets.
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Allergy Warning
Some people suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Frequent touching might lead to skin redness. It is best to use protective gloves.
Choking Hazard
Strictly keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are tragic.
Handling rules
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Data carriers
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.
Precision electronics
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Pacemakers
For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
