Shopping tips

A magnetic holder (magnet in a steel cup) is much stronger on one side than a bare magnet of the same dimensions. Thanks to this, the holder is more durable, resistant, and safer to mount. The threaded hole allows creating a functional mounting point in seconds.
The most important rule is choosing the appropriate length of the screw being screwed in. If the screw reaches the bottom of the bushing and is further tightened forcefully, it will destroy the magnet. You can use a spacer washer or lock nut to limit screwing depth.
These holders are commonly used in industry, advertising, and construction for quick mounting. They allow mounting without drilling in steel substrate, which is crucial in rented spaces. In the workshop, they can serve as mounting points for tools or measuring instruments.
This value applies to perfect adherence with the entire magnet surface. Air gap (rust, paint, dirt) also drastically lowers holding power. We always recommend choosing a magnet with power reserve, especially if the surface is not ideal.
Standard coating effectively protects against moisture in indoor conditions. For outdoor applications, we recommend additional protection with varnish or choosing a rubberized (hermetic) version. The whole is well protected for standard workshop and industrial applications.

Strengths as well as weaknesses of rare earth magnets.

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

  • They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
  • They do not lose their magnetic properties even under close interference source,
  • Thanks to the metallic finish, the coating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
  • Neodymium magnets achieve maximum magnetic induction on a their surface, which allows for strong attraction,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • In view of the possibility of accurate shaping and adaptation to individualized requirements, neodymium magnets can be created in a variety of geometric configurations, which expands the range of possible applications,
  • Wide application in innovative solutions – they are utilized in magnetic memories, drive modules, diagnostic systems, and complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems

Disadvantages of NdFeB magnets:

  • They are prone to damage 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 lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • 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
  • Due to limitations in realizing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
  • Due to neodymium price, their price is higher than average,

Best holding force of the magnet in ideal parameterswhat contributes to it?

Information about lifting capacity was determined for ideal contact conditions, assuming:

  • on a base made of mild steel, effectively closing the magnetic field
  • whose thickness reaches at least 10 mm
  • characterized by lack of roughness
  • under conditions of ideal adhesion (metal-to-metal)
  • under perpendicular force vector (90-degree angle)
  • in temp. approx. 20°C

Lifting capacity in real conditions – factors

During everyday use, the actual holding force depends on a number of factors, presented from the most important:

  • Distance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
  • Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
  • Material composition – different alloys reacts the same. Alloy additives weaken the attraction effect.
  • Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
  • Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.

* Lifting capacity was measured by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance {between} the magnet’s surface and the plate decreases the lifting capacity.

Precautions when working with NdFeB magnets

Dust is flammable

Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Do not underestimate power

Handle with care. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.

GPS and phone interference

Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a separation from your phone, tablet, and GPS.

Permanent damage

Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. This process is irreversible.

Beware of splinters

Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Danger to pacemakers

For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

This is not a toy

Neodymium magnets are not suitable for play. Swallowing several magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Skin irritation risks

Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, cease handling magnets and use protective gear.

Threat to electronics

Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).

Bone fractures

Pinching hazard: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
