Frequently asked questions

Which magnetic holder is suitable for moving metal parts in a workshop?
Choose a device designed for the intended handling task and check its rated conditions, attachment point and the steel being gripped. A basic permanent-magnet holder is not a certified device for lifting a load over people.
How do I choose a holder for hanging a heavy item and check its real grip?
Compare the catalogue pull rating with the actual steel thickness, surface condition, gap and load direction. Grip along a vertical surface differs from perpendicular pull. Add an independent mechanical safeguard where falling would cause harm.
Which magnetic holders can be used outdoors?
Check the coating, housing and permitted operating conditions on the individual product card. Rubber can help protect a painted surface, but do not assume that every holder is suitable for permanent immersion or salt spray.
How should I choose a strong threaded holder for field work?
Select an internal or external thread to match the part being attached. Then check the holder dimensions, pull rating, surface condition and moisture protection. Dirt and gaps can reduce practical grip.

It is a ready-made mounting element that allows quick creation of a magnetic point. Mounting consists of inserting the screw into the hole and securing with a nut (e.g., wing nut). 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 magnet itself is protected by a steel cup and is very resistant to impact.
Standard neodymium holders are adapted to work in temperatures up to 80°C. For furnaces, dryers, and powder coating shops, we recommend other types of magnets. Remember that even momentary overheating can weaken the holder.
Thread size (e.g., M6) is always given in the product name and technical specification. Exact screw dimensions can be found in the product technical table. It is a solid threaded connection, ready for use.
Yes, the steel housing (cup) focuses the magnetic field, significantly increasing attraction force on the active side. This force drops very quickly with increasing distance (air gap).

Advantages and disadvantages of neodymium magnets.

Benefits

Besides their remarkable field intensity, neodymium magnets offer the following advantages:
  • They retain magnetic properties for almost 10 years – the drop is just ~1% (in theory),
  • They are noted for resistance to demagnetization induced by presence of other magnetic fields,
  • A magnet with a smooth silver surface looks better,
  • Magnets are distinguished by impressive magnetic induction on the active area,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to modularity in forming and the ability to modify to client solutions,
  • Huge importance in modern technologies – they find application in HDD drives, electromotive mechanisms, medical equipment, and technologically advanced constructions.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:
  • At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
  • Do not exceed this material temperature limit: 80°C. Overheating may permanently weaken the magnet.
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mount.
  • Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these products are able to complicate diagnosis medical when they are in the body.
  • Due to complex production process, their price exceeds standard values,

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

Breakaway force was determined for ideal contact conditions, taking into account:
  • on a base made of structural steel, perfectly concentrating the magnetic flux
  • with a thickness no less than 10 mm
  • with an polished touching surface
  • under conditions of no distance (surface-to-surface)
  • during detachment in a direction vertical to the plane
  • at room temperature

Practical aspects of lifting capacity – factors

During everyday use, the real power results from several key aspects, listed from most significant:
  • Air gap (betwixt the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
  • Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
  • Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
  • Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
  • Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.

Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.

Warnings
Do not underestimate power

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

Thermal limits

Do not exceed the maximum operating temperature stated in the specifications of the particular product. The limit depends on the material, geometry and operating arrangement; there is no single threshold for all neodymium magnets. Overheating can permanently weaken a magnet.

Cards and drives

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

Choking Hazard

NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and necessitates immediate surgery.

Compass and GPS

GPS units and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.

Health Danger

For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.

Protective goggles

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Bodily injuries

Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!

Avoid contact if allergic

Studies show that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact or select coated magnets.

Do not drill into magnets

Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
