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.

This type of holder has a protruding threaded stud (screw), making it perfect for mounting in through holes. Thanks to this, you get a solid, magnetized mounting point without welding or gluing. They are commonly used in machine building, exhibition stands, lighting, and advertising.
Too strong tightening with a wrench can cause the stud to rotate in the cup or strip the thread. We recommend using spring washers to avoid the need for forceful tightening. The construction is durable and adapted to industrial conditions.
Above this temperature, the magnet may irreversibly lose some of its power. If you need resistance to higher temperatures, ask about special versions (H, SH). Remember that even momentary overheating can weaken the holder.
Holders are equipped with standard metric threads (e.g., M4, M6, M8, M10). Ensure thread length is sufficient to pass through the hole in your material and tighten the nut. It is a solid threaded connection, ready for use.
The magnetic system in a cup is more energy-efficient than the magnet itself of the same dimensions. However, such a system works point-wise and requires direct contact with metal.

Advantages as well as disadvantages of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:
  • They retain magnetic properties for nearly 10 years – the drop is just ~1% (based on simulations),
  • They maintain their magnetic properties even under external field action,
  • By using a shiny coating of gold, the element presents an professional look,
  • Magnets have exceptionally strong magnetic induction on the outer side,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Possibility of exact machining as well as adjusting to precise conditions,
  • Significant place in future technologies – they are commonly used in hard drives, electric drive systems, precision medical tools, and multitasking production systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:
  • They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
  • Neodymium magnets lose their strength 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
  • Limited possibility of producing nuts in the magnet and complex forms - recommended is a housing - magnet mounting.
  • Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical after entering the body.
  • Due to expensive raw materials, their price is relatively high,

Holding force characteristics

Optimal lifting capacity of a neodymium magnet – what affects it?

The specified lifting capacity refers to the maximum value, recorded under laboratory conditions, meaning:
  • on a base made of mild steel, perfectly concentrating the magnetic flux
  • whose thickness is min. 10 mm
  • with a plane cleaned and smooth
  • without any clearance between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • in temp. approx. 20°C

Practical aspects of lifting capacity – factors

In practice, the actual lifting capacity is determined by several key aspects, ranked from the most important:
  • Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
  • Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
  • Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
  • Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
  • Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
  • Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate decreases the holding force.

H&S for magnets
Magnet fragility

Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.

Machining danger

Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Serious injuries

Big blocks can smash fingers instantly. Under no circumstances place your hand between two strong magnets.

Warning for heart patients

Individuals with a pacemaker have to maintain an large gap from magnets. The magnetism can stop the operation of the implant.

Keep away from computers

Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.

Choking Hazard

Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.

Permanent damage

Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.

Sensitization to coating

Some people experience a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to a rash. We recommend use protective gloves.

Immense force

Be careful. Rare earth magnets attract from a long distance and snap with huge force, often quicker than you can react.

Threat to navigation

Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
