This toy stimulates manual development and teaches logical thinking through construction. It allows creating three-dimensional structures, which develops spatial vision. Building requires focus and planning, which positively affects concentration.
Our blocks are made of safe materials, however, due to small elements, they require an appropriate age of the user. The XMAG² set contains small steel balls (12.7 mm) that can be swallowed, so it is intended for children over 3 years of age (we recommend age 5+). The ZM XMAG2 210 elementów set ensures safe fun while maintaining basic safety rules.
The sticks and balls fit sets from other popular brands with the same dimensional standard. This allows for expanding the base of blocks without having to throw away old sets. Thanks to this, you can mix sets, which gives even more fun.
In the package, you will find magnetic rods serving as edges and metal balls being the nodes of the structure. The sticks attract the balls, creating stable and movable connections. The ZM XMAG2 210 elementów set weighing 0.03 g ensures an appropriate number of elements to start.
Cheap knock-offs often have weak magnets, making it impossible to build stable solids. In XMAG² blocks, the magnets are strong enough that buildings do not crumble under their own weight. Moreover, we use safe, non-toxic plastic that does not crack during play., which makes the blocks last for years.

Pros and cons of Nd2Fe14B magnets.

Advantages

Besides their immense strength, neodymium magnets offer the following advantages:
  • They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
  • Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
  • A magnet with a metallic gold surface is more attractive,
  • Magnetic induction on the working part of the magnet is maximum,
  • Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for functioning at temperatures approaching 230°C and above...
  • Possibility of accurate machining and adjusting to complex applications,
  • Versatile presence in modern industrial fields – they are used in hard drives, brushless drives, medical devices, as well as complex engineering applications.
  • Compactness – despite small sizes they provide effective action, making them ideal for precision applications

Cons

Characteristics of disadvantages of neodymium magnets: tips and applications.
  • Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
  • 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
  • Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
  • We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex forms.
  • Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these products are able to disrupt the diagnostic process medical after entering the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum holding power of the magnet – what it depends on?

Holding force of 0.03 kg is a theoretical maximum value performed under specific, ideal conditions:
  • using a plate made of mild steel, acting as a magnetic yoke
  • possessing a thickness of minimum 10 mm to avoid saturation
  • characterized by even structure
  • without any insulating layer between the magnet and steel
  • for force acting at a right angle (pull-off, not shear)
  • at temperature approx. 20 degrees Celsius

Practical aspects of lifting capacity – factors

It is worth knowing that the working load may be lower influenced by elements below, starting with the most relevant:
  • Air gap (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
  • Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
  • Plate thickness – insufficiently thick plate does not close the flux, causing part of the flux to be wasted into the air.
  • Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
  • Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
  • Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.

Warnings
Heat sensitivity

Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.

Product not for children

NdFeB magnets are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.

Powerful field

Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.

Electronic devices

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

Fire risk

Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

GPS and phone interference

An intense magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Magnet fragility

Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.

Serious injuries

Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.

Pacemakers

For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to work with the magnets.

Avoid contact if allergic

Studies show that nickel (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact or choose coated magnets.
