Magnetic properties of material
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Pros and cons of neodymium magnets.
Apart from their strong holding force, neodymium magnets have these key benefits:
- They retain full power for almost ten years – the loss is just ~1% (in theory),
- They have excellent resistance to weakening of magnetic properties when exposed to external fields,
- A magnet with a shiny silver surface looks better,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Due to the possibility of precise molding and customization to unique requirements, magnetic components can be created in a variety of forms and dimensions, which makes them more universal,
- Wide application in advanced technology sectors – they are utilized in computer drives, motor assemblies, medical devices, also other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Cons of neodymium magnets and ways of using them
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power 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 stability even at temperatures 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 stable to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complex forms - preferred is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Maximum lifting capacity of the magnet – what contributes to it?
Information about lifting capacity was defined for the most favorable conditions, including:
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- with zero gap (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
In practice, the actual lifting capacity is determined by several key aspects, presented from crucial:
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
* Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance {between} the magnet’s surface and the plate lowers the holding force.
Warnings
Magnetic interference
Note: rare earth magnets produce a field that interferes with sensitive sensors. Keep a separation from your mobile, device, and GPS.
Demagnetization risk
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Machining danger
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Serious injuries
Large magnets can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Electronic devices
Data protection: Strong magnets can ruin data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Keep away from children
These products are not suitable for play. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Conscious usage
Be careful. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can react.
Nickel coating and allergies
A percentage of the population suffer from a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Frequent touching can result in an allergic reaction. We recommend use safety gloves.
Protective goggles
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Pacemakers
Patients with a pacemaker should keep an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
