Product information
Playfully discover the world of magnetism with the magnet liquid from

The liquid iron is ideal for great experiments at home or at school and provides a very special aha experience in the context of natural science subjects.

Buy our ferrofluid and discover how magnetic particles come to life and create bizarre shapes.

A special kind of visual phenomenon.

From a purely visual point of view, the ferrofluid is a completely normal liquid that resembles black oil. But in the vicinity of a magnet, whimsical shapes arise and abstract peaks form almost as if the magnetic liquid were coming to life.
That amazes children as well as adults.
All of this is based on the magnetic properties of our ferrofluid: the finest iron particles with a size of approx. 10 nanometers are in the magnetic liquid (a nanometer is a millionth of a millimeter).
As ferromagnetic elements, they react enormously to magnetic fields and change the shape of the substance through the magnetic forces.
Of course, these iron particles are coated with a special protective layer so that they do not clump together.

Buy ferrofluid from
  • Vial with approx. 10 or 60 ml ferrofluid
  • Can be used multiple times
  • Including pipette for easy removal / return
  • Also available in larger numbers

Tip: The liquid iron forms significantly denser and more pointed structures with stronger magnetic fields.
The more magnetic liquid and the bigger the magnet, the more amazing the figures!

Handling advice:
Caution: The ferrofluid has properties comparable to those of motor oil in terms of pollution and can therefore leave stains on skin, clothing and surfaces that are difficult or impossible to remove (in the case of textiles).
For safety's sake, wear protective clothing, protective goggles and gloves during use and cover surfaces thoroughly!
These protective accessories are not included in the scope of delivery.
In the event of skin contact, clean immediately with soap and water!

  • The product conforms to the European RoHS Community legislation

    The product conforms to the European RoHS Community legislation The product conforms to the European RoHS Community legislation (2002/95/EG - RoHS - Restriction of Hazardous Substances) relating to the use and the employment of certain hazardous substances in electrical and electronic devices.
    No subject to registration under the REACH Regulation.
  • Determination of the magnetic force

    The adhesive force of our magnets is determined at room temperature on a polished plate made of steel S235JR (ST37) with a thickness of 10 mm by the vertical withdrawal of the magnet (1kg ~ 10 N). A different value down to -10% compared to the specified value is possible in exceptional cases. In general, the value is exceeded. Please note that for thinner, painted and not absolute plan undergrounds the adhesive force represents only one raction of the specified values.
