Field Strength

Other proposals

The steel cup acts as an armature, concentrating the magnetic flux and increasing capacity even several times. Moreover, the metal housing protects the brittle neodymium magnet from cracking upon impact. 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. Neodymium magnets are brittle, and direct pressure from a screw can cause them to crack or detach. 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. Ideal for fixing lighting on machine tools and welding tables.
The stated force is the maximum laboratory value obtained on a clean, smooth sheet. Air gap (rust, paint, dirt) also drastically lowers holding power. For side detachment (sliding), the force is only approx. 1/3 of nominal capacity.
Steel cups are usually coated with a layer of nickel (shiny) or zinc (matte/bright), providing basic protection. However, these are not fully stainless products and may corrode with constant contact with water. The whole is well protected for standard workshop and industrial applications.

Pros as well as cons of Nd2Fe14B magnets.

Advantages

Apart from their strong magnetism, neodymium magnets have these key benefits:
  • They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • They have excellent resistance to magnetic field loss as a result of external fields,
  • Thanks to the shimmering finish, the surface of nickel, gold-plated, or silver gives an aesthetic appearance,
  • They feature high magnetic induction at the operating surface, making them more effective,
  • 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...
  • Considering the potential of accurate forming and adaptation to specialized requirements, magnetic components can be produced in a broad palette of forms and dimensions, which increases their versatility,
  • Universal use in electronics industry – they are utilized in mass storage devices, electric drive systems, medical devices, as well as multitasking production systems.
  • Thanks to their power density, small magnets offer high operating force, with minimal size,

Weaknesses

Disadvantages of neodymium magnets:
  • They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
  • When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and 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 during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • Due to limitations in realizing threads and complex shapes in magnets, we recommend using casing - magnetic holder.
  • Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
  • Due to neodymium price, their price exceeds standard values,

Holding force characteristics

Magnetic strength at its maximum – what affects it?

Magnet power was determined for optimal configuration, taking into account:
  • using a plate made of mild steel, acting as a magnetic yoke
  • whose transverse dimension equals approx. 10 mm
  • characterized by lack of roughness
  • without the slightest air gap between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • in stable room temperature

Lifting capacity in practice – influencing factors

Please note that the working load will differ depending on the following factors, in order of importance:
  • Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
  • Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
  • Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
  • Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.

Safe handling of neodymium magnets
Powerful field

Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.

Protect data

Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.

Flammability

Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Medical interference

People with a pacemaker have to keep an large gap from magnets. The magnetic field can interfere with the operation of the implant.

Material brittleness

Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.

Keep away from electronics

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

Warning for allergy sufferers

Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease working with magnets and wear gloves.

Permanent damage

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

Choking Hazard

Adult use only. Small elements pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.

Hand protection

Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
