Turbomag XT-6 is an ideal solution for petrol, gas, and hybrid cars. It optimizes engine operation in every power mode, which is important for sequential installations. It is a complete Multimag set, containing elements for the fuel line and air intake.
The action of the magnetic field on air makes oxygen more chemically reactive. It increases engine efficiency, improves dynamics, and reduces harmful exhaust emissions. Comprehensive action on fuel and oxygen ensures the best performance and maximum savings.
Thanks to more efficient mixture combustion, the engine gradually cleans itself of lingering deposits. Spark plugs stay clean longer, guaranteeing a sure start. The engine runs more evenly, quietly, and responds more smoothly to the gas pedal.
Assembly is very simple and takes about 10-15 minutes without using tools. Attach smaller overlays on the fuel hose (supply) and larger ones on the air pipe (after the filter). No wires need to be cut or electronics/car computer interfered with.
The device has no moving parts, requires no service or cartridge replacement. Magnets are resistant to high temperatures prevailing under the engine hood. You can easily transfer the set to a new car when selling the old one.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
  • They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
  • By covering with a smooth layer of silver, the element presents an professional look,
  • Magnetic induction on the working layer of the magnet remains maximum,
  • 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...
  • Thanks to flexibility in designing and the capacity to modify to client solutions,
  • Key role in modern industrial fields – they are utilized in data components, electric motors, advanced medical instruments, also industrial machines.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Limitations

Cons of neodymium magnets and proposals for their use:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in force. 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 while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
  • Limited possibility of making threads in the magnet and complex shapes - preferred is cover - magnetic holder.
  • Possible danger to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical in case of swallowing.
  • With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Magnetic strength at its maximum – what it depends on?

The force parameter is a result of laboratory testing conducted under standard conditions:
  • with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
  • with a thickness no less than 10 mm
  • with a plane perfectly flat
  • under conditions of gap-free contact (metal-to-metal)
  • under perpendicular application of breakaway force (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Determinants of lifting force in real conditions

Bear in mind that the working load may be lower influenced by the following factors, starting with the most relevant:
  • Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
  • Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
  • Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Safe handling of neodymium magnets
Allergic reactions

Certain individuals have a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Extended handling might lead to skin redness. We strongly advise wear protective gloves.

Fragile material

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.

Choking Hazard

Always keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are fatal.

Do not overheat magnets

Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).

Pinching danger

Large magnets can smash fingers instantly. Do not put your hand between two attracting surfaces.

Flammability

Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Powerful field

Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and respect their force.

Phone sensors

A strong magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.

Electronic hazard

Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Medical implants

For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
