  • the breaking force of separation of the adhesive joint 32 is selected to be at least twice higher than the magnetic attraction force to a steel/metal surface of the flexible plastic (vinyl, for example) having the magnetic particles or twice higher than the magnetic at-traction force of fibrous fabric with magnetic particles in the form of impregnation with acrylate latex having the dispersed magnetic particles.
  • the panels 19 and 21 are being described utilizing glass and metal in their structure, it should be understood that the magnetic panels of the invention can utilize various materials such as, for example ceramic, wood, various plastics, rubber, textile, leather, stone, pressed craft paper and any combination thereof. In actuality, any natural or synthetic glueable materials or their combination can be used for the formation and use of the magnetic panels of the invention.
  • one or more magnetic particles are secured within at least at one of the front side 14 or the inner side 16 of the base by means of an adhesive joint 32, such as a glue which can be for example one- and two-component polyurethane adhesive or epoxy resin.
  • an adhesive joint 32 such as a glue which can be for example one- and two-component polyurethane adhesive or epoxy resin.
  • Alternative methods include use of a mechanical fixing device, or by embedding (implementing in the form of a magnetic powder 34) of one or more magnetic particles into the base. Use of other conventional methods or any combination of the above-discussed approaches are within the scope of the invention.
  • the magnetic particles 18 are provided characterized by maximum energy product (BH)max within the range between 2,0 and 100,00 kJ/m3.
  • Figs. 6A and 6B illustrate a base 22 made from a pressed craft paper 42 extending between two water resistant layers 40 and impregnated with the magnetic powder 34.
  • Fig. 9 illustrates another embodiment of the invention showing a bookshelf 45 attached to a wall 15 having the magnetically susceptible or steel exterior 23 by means of the magnetic panel 25 of the invention and the adhesive joint 32.
  • the adhesive joint 32 is a glue which can be for example one- and two-component polyurethane adhesive or epoxy resin.
  • the present invention exhibits a substantial number of advantages compared to the known prior art, for example, by providing simple installation and removal of the panel 10. This makes it possible to change rapidly the appearance of the exterior of the building wall and interior of the premises.
  • Another important advantage of the invention is the absence of the requirement for the highly skilled labor used in the installation of the panels 10 and the need for special equipment.
  • Further advantage of the invention is producing the magnetic panels from a variety of materials and coatings such as for example, paper-layered plastic, glass, metal, ceramic, wood, rubber, textile, leather, stone, pressed craft paper and any combination thereof (practically any natural or synthetic glueable materials or their combination, or any suitable simple or complex object, including electronic devices).
  • the possibility of arranging the magnetic panels in various combinations on a wall of a building is also very beneficial.
