Shopping tips

Ionizers Turbomag XT-4, produced with strong NdFeB magnets, are used in diesel engines, heating systems, and tap water installations. For diesel engines, they work by ionizing the fuel, which organizes its particles, enhancing burn efficiency. This allows for up to ten to twenty percent reduction in fuel consumption, about seven to eleven percent boost in engine performance, and up to 50% reduction in harmful emissions such as carbon monoxide, NOx, and hydrocarbons. Mounting is done on the fuel filter or on fuel lines, where magnets capture ferromagnetic impurities, purifying the fuel and removing them with each replacement. The effects are noticeable after only ten to fifteen kilometers of driving, due to improved vehicle dynamics. In heating installations and tap water systems, the Turbomag XT-4 acts as a magnetic ionizer, which neutralizes ions that cause scale buildup, avoiding pipe blockages, and dissolving existing deposits. This improves heating efficiency and reduces rust risk. Results appear after approximately thirty days of use.Benefits include: simple mounting, durability thanks to neodymium magnets, and lower energy and fuel bills. It is important to install the device in accordance with the manufacturer's guidelines, e.g., on the fuel line or on the heating pipe, to achieve optimal performance.Note: Strong neodymium magnets can be brittle and may interfere with electronic devices such as mobile phones, laptops, or magnetic cards. Keep them away from such devices and out of reach of children, due to the choking hazard.It is advised to use only authentic products from trusted manufacturers such as Dhit, to guarantee effective operation.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their durability, neodymium magnets are valued for these benefits:

  • They have unchanged lifting capacity, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
  • Their ability to resist magnetic interference from external fields is notable,
  • The use of a decorative nickel surface provides a smooth finish,
  • They possess strong magnetic force measurable at the magnet’s surface,
  • Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
  • With the option for fine forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
  • Significant impact in new technology industries – they are used in hard drives, rotating machines, medical equipment or even high-tech tools,
  • Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,

Disadvantages of rare earth magnets:

  • They may fracture when subjected to a powerful impact. If the magnets are exposed to physical collisions, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and additionally enhances its overall resistance,
  • High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
  • They rust in a moist environment – during outdoor use, we recommend using moisture-resistant magnets, such as those made of non-metallic materials,
  • Limited ability to create precision features in the magnet – the use of a mechanical support is recommended,
  • Safety concern due to small fragments may arise, if ingested accidentally, which is crucial in the protection of children. Additionally, tiny components from these magnets can complicate medical imaging after being swallowed,
  • In cases of large-volume purchasing, neodymium magnet cost may be a barrier,

Breakaway strength of the magnet in ideal conditionswhat contributes to it?

The given pulling force of the magnet means the maximum force, determined in ideal conditions, that is:

  • with the use of low-carbon steel plate serving as a magnetic yoke
  • of a thickness of at least 10 mm
  • with a polished side
  • with zero air gap
  • with vertical force applied
  • under standard ambient temperature

Determinants of lifting force in real conditions

The lifting capacity of a magnet is determined by in practice the following factors, ordered from most important to least significant:

  • Air gap between the magnet and the plate, because even a very small distance (e.g. 0.5 mm) causes a drop in lifting force of up to 50%.
  • Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
  • Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
  • Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
  • Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
  • Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. In addition, even a minimal clearance {between} the magnet and the plate lowers the lifting capacity.

Handle Neodymium Magnets Carefully

 Keep neodymium magnets away from youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Magnets made of neodymium are delicate and can easily crack and shatter.

Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

The magnet coating is made of nickel, so be cautious if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Avoid bringing neodymium magnets close to a phone or GPS.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are the strongest magnets ever invented. Their strength can surprise you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

Neodymium magnets will jump and touch together within a distance of several to almost 10 cm from each other.

Pay attention!
