Reducing Electromagnetic Fields | Create Your Healthy Home

To measure AC magnetic fields on your own, order a low-cost gaussmeter, such as the GaussMaster, from, 888-537-7363. Lower-cost gaussmeters may only measure up to 10 or 20 mG, but those numbers are already too high. With a lower cost, single-axis gaussmeter, you have to rotate it to get the highest reading at any given location.

Nov 10, 2006· Magnetic separations at very low magnetic field gradients (<100 tesla per meter) can now be applied to diverse problems, such as point-of-use water purification and the simultaneous separation of complex mixtures. High–surface area and monodisperse magnetite (Fe3O4) nanocrystals (NCs) were shown to respond to low fields in a size-dependent fashion.

Low Frequency Magnetic Shielding An Integrated Solution

fields by redirecting the magnetic field through the shielding material and away from the protected device. In the same fashion, devices that emit low frequency magnetic fields can also be isolated through the use of materials with high magnetic permeability.
