Field Strength

Other products

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 outer layer is hygienic acid-resistant steel, approved for food contact. The center is filled with NdFeB magnets and pole pieces, arranged to maximize the field on the tube surface. Thanks to this, the rod is durable, hygienic, and easy to keep clean.
Due to the high power of the magnet, direct removal of filings can be troublesome and time-consuming. You can use compressed air or special non-magnetic strippers (rings). For easier operation, it is worth considering ordering a rod in a version with a cleaning sleeve.
The Gauss value tells us how effectively and deeply the magnet will catch contaminants. Standard rods (~8000 Gs) are sufficient for catching screws, nails, and steel shavings. High induction is necessary when contaminants are microscopic or weakly magnetic.
We can produce a rod of non-standard length with any mounting termination. You can choose a mounting method consistent with your technical design. We ensure fast realization of special orders and technical advice.

Strengths and weaknesses of neodymium magnets.

Pros

Besides their exceptional strength, neodymium magnets offer the following advantages:
  • Their magnetic field remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
  • They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
  • A magnet with a metallic gold surface has better aesthetics,
  • Magnets exhibit excellent magnetic induction on the surface,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
  • Thanks to versatility in constructing and the capacity to adapt to individual projects,
  • Fundamental importance in future technologies – they are used in mass storage devices, electromotive mechanisms, medical devices, also other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions

Disadvantages

Cons of neodymium magnets: tips and applications.
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting 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 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
  • Limited ability of making nuts in the magnet and complicated shapes - preferred is a housing - magnet mounting.
  • Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices are able to be problematic in diagnostics medical after entering the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Detachment force of the magnet in optimal conditionswhat it depends on?

The declared magnet strength refers to the peak performance, recorded under ideal test conditions, meaning:
  • on a plate made of structural steel, optimally conducting the magnetic flux
  • whose thickness reaches at least 10 mm
  • characterized by lack of roughness
  • with direct contact (no impurities)
  • during pulling in a direction vertical to the plane
  • in stable room temperature

Determinants of practical lifting force of a magnet

Please note that the magnet holding may be lower depending on elements below, in order of importance:
  • Gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
  • Load vector – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
  • Steel thickness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
  • Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and holding force.
  • Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
  • Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).

Lifting capacity was measured by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.

Precautions when working with neodymium magnets
Data carriers

Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).

Medical interference

Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.

Avoid contact if allergic

A percentage of the population suffer from a hypersensitivity to nickel, which is the common plating for neodymium magnets. Prolonged contact can result in skin redness. We strongly advise use protective gloves.

Threat to navigation

A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to avoid breaking the sensors.

Demagnetization risk

Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.

This is not a toy

These products are not suitable for play. Eating a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires immediate surgery.

Material brittleness

NdFeB magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.

Handling guide

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

Serious injuries

Large magnets can crush fingers instantly. Under no circumstances put your hand betwixt two strong magnets.

Machining danger

Fire warning: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
