How to shield your house from home biology

Magnetic fieldsrate most materials unaffected.ic shielding materials have very high permeability and pull theic field lines forcing them to pass through them, thus reducing theic field values in the rest of the space. They are also very expensive. Materials such as copper, lead or aluminum are not suitable for shielding theic fields as many people believe

What isic field? Definition from

Anic field, sometimes referred to as an EM field, is generated when charged particles, such as electrons, are accelerated. All electrically charged particles are surrounded by electric fields. Charged particles in motion produceic fields. When the velocity of a charged particle changes, an EM field is produced.

WHO What areic fields?

Magnetic fields are created when electric current flows: the greater the current, the stronger theic field. An electric field will exist even when there is no current flowing. If current does flow, the strength of theic field will vary with power consumption but the electric field strength will be constant. Extract fromic fields published by the WHO Regional Office

James Clerk Maxwell derived a wave form of the electric andic equations, thus uncovering the wave like nature of electric andic fields and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave.
