One of the most relevant feature of geophysical techniques based on nuclear magnetic resonance is their ability to estimate the permeability of natural porous media, since other geophysical techniques, as the use of the ...

Magnetic energy losses and permeability have been investigated in laboratory prepared and commercial Mn-Zn sintered ferrites from quasi-static conditions up to 10 MHz. The mechanisms leading to energy dissipation, either ...

Neste trabalho foi obtida uma expressão algébrica que relaciona a permeabilidade magnética de um fio delgado retilíneo ferromagnético, com a força eletromotriz gerada nas suas extremidades pela variação no tempo de uma ...

In this presentation we will talk about Magnetism its characteristics, properties and classification, since most of the magnets that are currently used are artificial, this is because they can be manufactured with a greater ...

The pore structure of many carbonate formations is known to be very complex and heterogeneous. Heterogeneity is manifested by the presence of different types, sizes, and shapes of pores resulting from sedimentation and ...
