Light transmission, magnetodielectric and magnetoresistive effects in membranes based on hybrid magnetorheological suspensions in a static magnetic field superimposed on a low/medium frequency electric field

We manufacture membranes based on cotton fabric impregnated with a mixture of honey and carbonyl iron microparticles, with volume fractions of 2.5,5 and 10vol.%. An experimental setup is built to show that in a static magnetic field with intensities up to 37 kA/m the transmission of white light radiation generated by the light-emitting diodes (LEDs) of a LED lamp, is controllable. In addition, in a static magnetic field superimposed on a low and medium frequency electric field, magnetodielectric and magnetoresistive effects are induced. They depend on the volume fraction of the magnetizable phase, on the magnetic field intensity and on the frequency of the alternating electric field. However, they are independent on the incident light radiation. Due to the combined therapeutic effects of honey, carbonyl iron powder, magnetic field, and low and medium frequency electric fields, the results obtained in this work can be used for fabrication of devices that exploit the observed effects for the treatment of various diseases.
