This toy stimulates manual development and teaches logical thinking through construction. It allows creating three-dimensional structures, which develops spatial vision. It's creative entertainment for the whole family, connecting generations at a shared table.
The toy has the necessary certificates, but supervision of the youngest is key. 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+). We warn against the risk of swallowing magnets and recommend playing under adult supervision.
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.
The set consists of colorful magnetic sticks (with strong neodymium magnets at the ends) and nickel-plated steel balls. The balls serve as joints to which the magnetic ends of the rods attract. The ZM XMAG2 105 elementów set weighing 0.03 g ensures an appropriate number of elements to start.
Our blocks are distinguished by the use of NdFeB magnets with high energy density, which allows building larger structures. 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.

Advantages and disadvantages of neodymium magnets.

Pros

Besides their immense pulling force, neodymium magnets offer the following advantages:
  • They retain magnetic properties for around 10 years – the drop is just ~1% (according to analyses),
  • Magnets very well resist against loss of magnetization caused by ambient magnetic noise,
  • The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
  • They feature high magnetic induction at the operating surface, making them more effective,
  • 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...
  • Possibility of individual modeling as well as optimizing to defined conditions,
  • Key role in modern industrial fields – they are commonly used in magnetic memories, drive modules, medical devices, and modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions

Limitations

What to avoid - cons of neodymium magnets and proposals for their use:
  • At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's 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
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited ability of making nuts in the magnet and complicated shapes - preferred is cover - mounting mechanism.
  • Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Magnet power was defined for ideal contact conditions, taking into account:
  • using a plate made of mild steel, functioning as a magnetic yoke
  • whose transverse dimension equals approx. 10 mm
  • with a surface cleaned and smooth
  • with zero gap (no impurities)
  • under vertical force vector (90-degree angle)
  • at standard ambient temperature

Key elements affecting lifting force

In real-world applications, the actual lifting capacity is determined by many variables, listed from the most important:
  • Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
  • Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be wasted into the air.
  • Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
  • Plate texture – ground elements ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
  • Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was determined by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.

Safety rules for work with neodymium magnets
Operating temperature

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.

Conscious usage

Be careful. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.

Precision electronics

A strong magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Shattering risk

Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them breaking into shards.

Medical interference

Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to work with the magnets.

Threat to electronics

Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).

Crushing risk

Watch your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Mechanical processing

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

Warning for allergy sufferers

Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.

Keep away from children

Adult use only. Small elements pose a choking risk, leading to serious injuries. Store away from kids and pets.

Caution! More info about hazards in the article: Magnet Safety Guide.
