The EURO RTM standard magnets were the first magnetic components to introduce magnetic shuttering solutions to modern precast concrete production. With their compact design and reliable retaining force, they are still suitable for many shuttering tasks and are used today in numerous plants. The special shape allows for various accessory components to be slipped over and safely fixed in place through positive locking. For secure attachment of multifunctional slipon shuttering or the RATEC universal adapter set, as well as for installation into existing plywood shuttering. PROPERTIES Compact design High retaining force with minimal weight Smooth, easy to clean surfaces on all sides Crosssection with negative draft for creating pressurecontact fit with Ushaped side rail Insulated on all sides, only the contact surface is magnetic The special shape allows for various accessory components to be slipped over and safely fixed in place through positive locking.

For testing cardio-stimulators and other medical devices, a set of the magnetic field sources was designed having a magnetic flux density in the working area from 1 to 300 mT.

The magnetic system of this field source is also built on the principle of nested cylindrical Halbach-structures. An important feature is the presence of two motors, controlled independently, so it is possible to manage the change not only the magnitude but also the direction of the magnetic field. Because the device was designed for operation together with an optical microscope, the vertical size of the system near the working region is reduced to 90 mm. Stepper motors, that turn the two magnetic subsystems, are located on the sides of the casing

This type of magnetic systems is developed for NMR applications, but can also be used for other tasks requiring the highly homogeneous magnetic field in the significant working volume. The main magnetic system, built on the principle of dipole Halbach-structure, is complemented by the additional corrective system of magnetic elements, that allows to bring the homogeneity of the magnetic field to the level of 10-4 in the desired working volume.
