Quadro-rotating field mat

quadro mat

Quadro mat is build of 4 coils. Each coil has 50 turns (coils) of 0.4mm diameter cu wire. For instruction on how to construct the coil, please find the following link: Coil assembly. In order to use that mat you need have the freePEMF duo device. Only duo generates signal for quadro-rotating electro-magnetic field.


For more information see: Mat making.

You can also use mat as Helmholtz coils for body treatment. You need to turn one mat to different side in the pillowcase. Magnetic flux depends on distance between the coils. It should equal to the radius of a coil. For more information find picture below.
