Jak rozdzielać?
Nie próbuj odrywać magnesów siłą!
Zawsze zsuwaj je na bok krawędzi stołu.
Elektronika
Trzymaj z dala od dysków HDD, kart płatniczych i telefonów.
Rozruszniki Serca
Osoby z rozrusznikiem muszą zachować dystans min. 10 cm.
Nie dla dzieci
Ryzyko połknięcia. Połknięcie dwóch magnesów grozi śmiercią.
Kruchy materiał
Magnes to ceramika! Uderzenie o inny magnes spowoduje odpryski.
Do czego użyć tego magnesu?
Sprawdzone zastosowania dla wymiaru 15x10x2 mm
Elektronika i Czujniki
Idealny jako element wyzwalający dla czujników Halla oraz kontaktronów w systemach alarmowych. Płaski kształt (2mm) pozwala na ukrycie go w wąskich szczelinach obudowy.
Modelarstwo i Druk 3D
Stosowany do tworzenia niewidocznych zamknięć w modelach drukowanych 3D. Można go wprasować w wydruk lub wkleić w kieszeń zaprojektowaną w modelu CAD.
Meble i Fronty
Używany jako "domykacz" lekkich drzwiczek szafkowych, gdzie standardowe magnesy meblowe są za grube. Wymaga wklejenia w płytkie podfrezowanie.

Pros as well as cons of rare earth magnets.
Apart from their consistent magnetism, neodymium magnets have these key benefits:
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They have excellent resistance to magnetism drop as a result of external magnetic sources,
- By using a smooth layer of nickel, the element presents an proper look,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Possibility of custom forming as well as adapting to specific conditions,
- Fundamental importance in high-tech industry – they are commonly used in hard drives, electric drive systems, medical devices, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
What to avoid - cons of neodymium magnets: tips and applications.
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small components of these magnets 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
Detachment force of the magnet in optimal conditions – what affects it?
The lifting capacity listed is a measurement result executed under the following configuration:
- on a block made of structural steel, optimally conducting the magnetic field
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
Effective lifting capacity is influenced by specific conditions, including (from priority):
- Air gap (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
- 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).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
* Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance {between} the magnet and the plate decreases the holding force.

H&S for magnets
Electronic hazard
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
No play value
Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Store away from kids and pets.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.
Combustion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Do not overheat magnets
Watch the temperature. Exposing the magnet to high heat will destroy its properties and strength.
Hand protection
Large magnets can crush fingers instantly. Never put your hand between two attracting surfaces.
Handling guide
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
GPS and phone interference
A powerful magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Keep magnets near a device to avoid breaking the sensors.
Magnet fragility
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
