| 摘要 |
The invention relates to a device which has a support element (1) of substantially rectangular shape composed, for example, of a mattress, inside of which there is a band magnetised in permanent manner whose two faces have opposite polarities. In the support element, an electric winding (3) is also incorporated which has one or more turns of conductor material to form a solenoid, advantageously closed on an E.M.I. absorber device of in se known type, normally used to reduce the line radiations of digital signals. By means of the device according to the finding, the reduction of the noise magnetic field generated by a plurality of artificial sources is obtained along with a wave emitter apparatus comparable to a magnetotherapy device, capable of producing a sequence of magnetic impulses of low frequency and of variable amplitude and frequency.
