A magnetic rod is the basic element of building grate separators and magnetic filters. It is mounted in chutes, hoppers, and pipelines to protect production machines from failure. High magnetic induction on the surface allows catching the finest iron particles.
The outer layer is hygienic acid-resistant steel, approved for food contact. Inside there is a stack of strong neodymium magnets arranged in a special configuration (magnetic circuit). Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Metal contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. The most effective home method is using adhesive tape, which we wrap around the dirt and peel off. For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
Magnetic induction measured in Gauss (Gs) determines the density of magnetic flux on the rod surface. The economical version (8kGs) handles large pieces of metal perfectly. High Power versions (~12000-14000 Gs) are necessary for catching metallic dust, oxides, and stainless steel after processing.
We can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. We ensure fast realization of special orders and technical advice.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Advantages
Besides their stability, neodymium magnets are valued for these benefits:
  • Their strength remains stable, and after around ten years it drops only by ~1% (according to research),
  • They maintain their magnetic properties even under strong external field,
  • In other words, due to the smooth surface of silver, the element looks attractive,
  • Magnetic induction on the surface of the magnet turns out to be extremely intense,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
  • Possibility of individual creating as well as optimizing to concrete applications,
  • Key role in future technologies – they are used in computer drives, motor assemblies, diagnostic systems, and technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems
Disadvantages
Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
  • We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
  • Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical after entering the body.
  • With large orders the cost of neodymium magnets is economically unviable,

Lifting parameters

Maximum lifting force for a neodymium magnet – what it depends on?
Magnet power was determined for optimal configuration, including:
  • with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
  • with a cross-section of at least 10 mm
  • with a plane cleaned and smooth
  • with total lack of distance (without impurities)
  • under vertical application of breakaway force (90-degree angle)
  • at conditions approx. 20°C
What influences lifting capacity in practice
During everyday use, the real power results from many variables, listed from crucial:
  • Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to paint, rust or dirt).
  • Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
  • Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
  • Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Plate texture – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
  • Temperature – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the holding force.

Precautions when working with NdFeB magnets
Product not for children

Product intended for adults. Small elements can be swallowed, leading to serious injuries. Store out of reach of children and animals.

Do not overheat magnets

Regular neodymium magnets (N-type) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Serious injuries

Protect your hands. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Implant safety

Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.

GPS and phone interference

Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.

Nickel coating and allergies

Some people suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling can result in a rash. We strongly advise wear safety gloves.

Handling rules

Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.

Data carriers

Do not bring magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Mechanical processing

Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Beware of splinters

NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them shattering into small pieces.
