Frequently asked questions

How much will a magnetic holder hold in practice?
The catalogue value assumes full contact with smooth steel at least 10 mm thick and a perpendicular pull. Thinner sheet, paint, rust and surface irregularities reduce it considerably: on 1 mm sheet about half remains. Lifting and vertical mounting call for an additional safety margin.
Will a holder work on stainless steel?
Not on austenitic grades 304 and 316 — they are effectively non-magnetic. It will not work on aluminium, copper or brass either. Those materials need a mechanical gripper.
Which coating for which conditions?
Nickel-copper-nickel (NiCuNi) is the standard and covers most applications. Epoxy is used for damp environments and outdoor work, zinc is sufficient for dry interiors. Holders in a steel housing or in rubber also protect the magnet against impact.

Advantages and disadvantages of rare earth magnets.

Pros

Apart from their consistent holding force, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
  • They possess excellent resistance to weakening of magnetic properties due to external magnetic sources,
  • In other words, due to the aesthetic surface of silver, the element is aesthetically pleasing,
  • Magnetic induction on the top side of the magnet turns out to be exceptional,
  • 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 ability of free forming and customization to custom solutions, magnetic components can be produced in a variety of geometric configurations, which makes them more universal,
  • Wide application in future technologies – they find application in data components, electric motors, medical devices, also other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in small systems

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
  • Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - magnetic mount.
  • Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
  • With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

Holding force of 480.00 kg is a theoretical maximum value conducted under the following configuration:
  • using a sheet made of high-permeability steel, serving as a magnetic yoke
  • whose thickness equals approx. 10 mm
  • with a plane perfectly flat
  • without the slightest insulating layer between the magnet and steel
  • during detachment in a direction perpendicular to the mounting surface
  • in neutral thermal conditions

Lifting capacity in real conditions – factors

Please note that the magnet holding may be lower influenced by elements below, in order of importance:
  • Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
  • Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
  • Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Plate material – mild steel attracts best. Alloy steels lower magnetic permeability and holding force.
  • Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was determined with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the load capacity.

Safe handling of NdFeB magnets
Safe operation

Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.

This is not a toy

Always keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are very dangerous.

Mechanical processing

Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.

Operating temperature

Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Pacemakers

Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Keep away from computers

Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can irreversibly ruin these devices and erase data from cards.

Material brittleness

Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.

Metal Allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.

Hand protection

Big blocks can break fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.

GPS Danger

An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.
