Magnetic Induction

Other deals

A magnetic rod is the basic element of building grate separators and magnetic filters. Its task is separation (separation) of metal filings from the transported material. High magnetic induction on the surface allows catching the finest iron particles.
The rod consists of a cover tube made of high-quality acid-resistant steel (AISI 304 or 316). The core is a precise magnetic system generating high induction (Gauss). Such construction ensures full resistance to corrosion, water, oils, and acids.
Metal contaminants are strongly attracted, so removing them with a bare hand or glove can be difficult. You can use compressed air or special non-magnetic strippers (rings). In industry, cover tubes (so-called Easy Clean system) are used, from which the magnetic insert slides out.
The more Gauss, the smaller and more weakly magnetic particles will be effectively caught. The economical version (8kGs) handles large pieces of metal perfectly. High induction is necessary when contaminants are microscopic or weakly magnetic.
We fulfill individual orders for bars perfectly matched to your machine or separator. The rod end is strictly adapted to the fastening system in your device. We ensure fast realization of special orders and technical advice.

Advantages and disadvantages of neodymium magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
  • Neodymium magnets are distinguished by highly resistant to demagnetization caused by external magnetic fields,
  • Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to the option of precise forming and customization to custom needs, neodymium magnets can be manufactured in a variety of geometric configurations, which makes them more universal,
  • Significant place in modern industrial fields – they serve a role in mass storage devices, motor assemblies, precision medical tools, as well as other advanced devices.
  • Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
  • Limited ability of producing nuts in the magnet and complicated shapes - preferred is casing - magnetic holder.
  • Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
  • High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum lifting capacity of the magnetwhat it depends on?

Magnet power was defined for optimal configuration, taking into account:
  • with the application of a sheet made of special test steel, ensuring full magnetic saturation
  • possessing a massiveness of at least 10 mm to avoid saturation
  • characterized by lack of roughness
  • under conditions of ideal adhesion (metal-to-metal)
  • under perpendicular application of breakaway force (90-degree angle)
  • at standard ambient temperature

Determinants of lifting force in real conditions

In real-world applications, the actual holding force results from several key aspects, presented from crucial:
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
  • Base massiveness – too thin steel causes magnetic saturation, causing part of the power to be lost to the other side.
  • Steel grade – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
  • Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
  • Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.

Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.

H&S for magnets
Life threat

Individuals with a pacemaker must keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.

Keep away from children

NdFeB magnets are not suitable for play. Eating several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.

Safe distance

Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.

Flammability

Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.

Fragile material

Neodymium magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them cracking into small pieces.

Phone sensors

GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Thermal limits

Keep cool. NdFeB magnets are sensitive to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).

Crushing force

Danger of trauma: The attraction force is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Immense force

Be careful. Neodymium magnets attract from a distance and connect with massive power, often faster than you can react.

Allergy Warning

Certain individuals experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Extended handling can result in skin redness. It is best to use safety gloves.
