Shopping tips

The presented product is a very strong rod magnet, composed of modern NdFeB material, which, with dimensions of Ø8x1.5 mm, guarantees optimal power. The MW 8x1.5 / N38 model features high dimensional repeatability and industrial build quality, making it an ideal solution for professional engineers and designers. As a magnetic rod with impressive force (approx. 0.66 kg), this product is in stock from our warehouse in Poland, ensuring lightning-fast order fulfillment. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in typical operating conditions, ensuring an aesthetic appearance and durability for years.
This model is perfect for building generators, advanced Hall effect sensors, and efficient filters, where maximum induction on a small surface counts. Thanks to the pull force of 6.47 N with a weight of only 0.57 g, this rod is indispensable in electronics and wherever low weight is crucial.
Since our magnets have a tolerance of ±0.1mm, the recommended way is to glue them into holes with a slightly larger diameter (e.g., 8.1 mm) using two-component epoxy glues. To ensure stability in industry, anaerobic resins are used, which are safe for nickel and fill the gap, guaranteeing high repeatability of the connection.
Magnets N38 are suitable for 90% of applications in modeling and machine building, where excessive miniaturization with maximum force is not required. If you need even stronger magnets in the same volume (Ø8x1.5), contact us regarding higher grades (e.g., N50, N52), however, N38 is the standard in continuous sale in our store.
This model is characterized by dimensions Ø8x1.5 mm, which, at a weight of 0.57 g, makes it an element with high magnetic energy density. The value of 6.47 N means that the magnet is capable of holding a weight many times exceeding its own mass of 0.57 g. The product has a [NiCuNi] coating, which secures it against external factors, giving it an aesthetic, silvery shine.
Standardly, the magnetic axis runs through the center of the cylinder, causing the greatest attraction force to occur on the bases with a diameter of 8 mm. Such an arrangement is most desirable when connecting magnets in stacks (e.g., in filters) or when mounting in sockets at the bottom of a hole. On request, we can also produce versions magnetized diametrically if your project requires it.

Pros and cons of NdFeB magnets.

In addition to their pulling strength, neodymium magnets provide the following advantages:

  • They retain attractive force for almost 10 years – the drop is just ~1% (based on simulations),
  • They are extremely resistant to demagnetization induced by presence of other magnetic fields,
  • Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold, or silver gives an clean appearance,
  • Magnets are characterized by impressive magnetic induction on the outer side,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
  • Thanks to versatility in constructing and the ability to modify to unusual requirements,
  • Key role in high-tech industry – they are utilized in magnetic memories, motor assemblies, precision medical tools, and industrial machines.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Disadvantages of NdFeB magnets:

  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • We recommend cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
  • Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Best holding force of the magnet in ideal parameterswhat it depends on?

The load parameter shown concerns the peak performance, measured under optimal environment, meaning:

  • using a base made of low-carbon steel, functioning as a ideal flux conductor
  • possessing a massiveness of minimum 10 mm to avoid saturation
  • characterized by lack of roughness
  • without any clearance between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at temperature approx. 20 degrees Celsius

What influences lifting capacity in practice

Effective lifting capacity impacted by specific conditions, mainly (from priority):

  • Clearance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Direction of force – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
  • Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
  • Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

* Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance {between} the magnet and the plate decreases the lifting capacity.

H&S for magnets

This is not a toy

Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.

Finger safety

Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Eye protection

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

Operating temperature

Watch the temperature. Exposing the magnet to high heat will permanently weaken its properties and pulling force.

ICD Warning

People with a heart stimulator have to keep an safe separation from magnets. The magnetism can stop the functioning of the life-saving device.

Data carriers

Data protection: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).

Mechanical processing

Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.

GPS Danger

Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.

Warning for allergy sufferers

Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease handling magnets and use protective gear.

Handling guide

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Security!
