The present invention relates to electromagnetic equipment for increasing the tissue elasticity used particularly in the cosmetic and the medical field.. The electromagnetic according of the invention contains a support (A) a coil-applicator (B) for the application of the electromagnetic field a filter (G) for filtering the currents harmonics applied to a device (D) generating an electromagnetic field the ensemble made up of the device (D) the filter (C) and the coil-applicator (B) being constructed to generate inside the coil-applicator (B) in an X area an uniform electromagnetic field with the induction between 0.7-0.8 mT with a variation between 5-10% in the area subjected by the electromagnetic field on a distance of 1 cm around the same point on a larger volume in the treated areas produced by a current of 400 mA of a frequency between 7 and 8 Hz preferably 7.69 Hz with field lines perpendicular on the surface of the skin and wherein the coil-applicator (B) in which it applies an uniform electromagnetic field at right angles to the localized area next to their cell tissue it is composed of two magnetic cores one inner (5) and one outer (6) in the form of a circle and a housing (7) around each core (5 6) being wired a small coil (9) and respectively a large coil (10) coupled in series with one another so it can allow an induction of 06-08mT in the treatment area and a uniform magnetic field perpendicular to the treated surface for example the skin the output of the large coil (10) being connected to the input of the small coil (9) and the input of the large coil (10) and the output of the small coil (9) being electrically connected to the small unit (D) electronically generating the electromagnetic field through the filter (C) so it can be filtered the harmonics current flowing in the device (D).
