Magnetic Field

The XT-6 set was developed specifically for engines powered by petrol and gas (LPG/CNG). It works equally effectively on petrol and gas, improving the parameters of both fuels. It is a complete Multimag set, containing elements for the fuel line and air intake.
Using a magnetizer on the intake improves the quality of the fuel-air mixture in the cylinder. This results in better mixture burn-up in cylinders and fewer unburned residues. Comprehensive action on fuel and oxygen ensures the best performance and maximum savings.
Yes, better combustion means significantly less carbon depositing in the combustion chamber. It protects expensive components like the catalyst or GPF filter from clogging. 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. The instruction indicates to place magnetizers as close to the engine as possible (intake manifold and injection rail). No wires need to be cut or electronics/car computer interfered with.
The device has no moving parts, requires no service or cartridge replacement. Magnetic field power is stable for decades, ensuring constant efficiency. You can easily transfer the set to a new car when selling the old one.

Pros as well as cons of neodymium magnets.

Advantages

Apart from their strong holding force, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
  • They feature excellent resistance to magnetic field loss as a result of opposing magnetic fields,
  • In other words, due to the aesthetic finish of nickel, the element gains visual value,
  • The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Thanks to flexibility in shaping and the ability to customize to complex applications,
  • Huge importance in modern industrial fields – they serve a role in data components, electric drive systems, medical devices, as well as other advanced devices.
  • Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,

Limitations

Disadvantages of NdFeB magnets:
  • To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
  • When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
  • When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
  • Due to limitations in producing threads and complex forms in magnets, we propose using cover - magnetic mount.
  • Possible danger related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical after entering the body.
  • With budget limitations the cost of neodymium magnets is economically unviable,

Lifting parameters

Breakaway strength of the magnet in ideal conditionswhat affects it?

The load parameter shown refers to the limit force, measured under optimal environment, namely:
  • with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with a surface perfectly flat
  • with total lack of distance (without impurities)
  • for force acting at a right angle (pull-off, not shear)
  • at ambient temperature room level

Practical lifting capacity: influencing factors

It is worth knowing that the magnet holding will differ influenced by elements below, in order of importance:
  • Clearance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
  • Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
  • Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
  • Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
  • Heat – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Warnings
Conscious usage

Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can move away.

Magnetic interference

Remember: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.

Dust explosion hazard

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

Data carriers

Device Safety: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).

Crushing force

Pinching hazard: The pulling power is so great that it can cause blood blisters, pinching, and broken bones. Use thick gloves.

Keep away from children

These products are not suitable for play. Eating a few magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.

Medical implants

Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.

Maximum temperature

Watch the temperature. Heating the magnet to high heat will destroy its properties and strength.

Material brittleness

Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.

Warning for allergy sufferers

Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.
