If the wood is compacted, its density changes depending on the degree of pressure. Wood is also subjected to radioactive i

Interaction between the Electromagnetic Field and Wood. Main Features of Dielectric Properties of Wce of these components on wood is different. The influence of the magnetic field on wood is negligible and is not taken into consideration for practical purposes. The influence of the electric field on wood is very strong as the interaction between them results in the creation of electric currents in the material.

These changes result in changes of the dielectric properties of the wood, particularly at frequencies at which water possesses anomalously high dielectric parameters. Water is the ingredient that changes the dielectric properties of wood the most and in many cases determines them.
