Magnetic Induction

Other deals

This product serves to effectively catch ferromagnetic contaminants from bulk and liquid products. 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). 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 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.

Strengths as well as weaknesses of neodymium magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They do not lose magnetism, even after nearly 10 years – the drop in strength is only ~1% (based on measurements),
  • They are noted for resistance to demagnetization induced by presence of other magnetic fields,
  • In other words, due to the reflective finish of silver, the element gains visual value,
  • They feature high magnetic induction at the operating surface, which increases their power,
  • Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
  • Considering the option of accurate molding and customization to custom solutions, neodymium magnets can be modeled in a broad palette of forms and dimensions, which expands the range of possible applications,
  • Fundamental importance in advanced technology sectors – they are used in magnetic memories, brushless drives, diagnostic systems, as well as multitasking production systems.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
  • Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Due to limitations in realizing nuts and complex forms in magnets, we propose using casing - magnetic mechanism.
  • Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Optimal lifting capacity of a neodymium magnetwhat it depends on?

The force parameter is a measurement result performed under the following configuration:
  • on a plate made of structural steel, optimally conducting the magnetic flux
  • whose thickness reaches at least 10 mm
  • with an ideally smooth contact surface
  • under conditions of ideal adhesion (surface-to-surface)
  • for force applied at a right angle (pull-off, not shear)
  • at temperature approx. 20 degrees Celsius

Magnet lifting force in use – key factors

Effective lifting capacity is influenced by working environment parameters, including (from most important):
  • Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
  • Steel thickness – too thin sheet does not close the flux, causing part of the flux to be lost into the air.
  • Plate material – mild steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
  • Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
  • Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets
Safe operation

Before starting, read the rules. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.

Compass and GPS

Be aware: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.

Do not overheat magnets

Control the heat. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Skin irritation risks

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.

Warning for heart patients

People with a heart stimulator have to keep an large gap from magnets. The magnetism can disrupt the operation of the implant.

Product not for children

Always keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are life-threatening.

Beware of splinters

Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets leads to them shattering into shards.

Keep away from computers

Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).

Fire risk

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Crushing risk

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
