A new reasoning-based approach for measuring the magnetic field emitted by portable computers

This paper explores a new reasoning-based approach for measuring the extremely low frequency magnetic field emitted by a portable computer. The introduced approach and the widely accepted TCO standard are compared each other and discussed. This comparison shows that the well-known magnetic field measurement TCO standard has important limitations and disadvantages. In fact, the new reasoning-based approach obtains measurement results of the extremely low frequency magnetic field which are closer to the working conditions of the portable computers' users. Accordingly, the introduced measurement methodology is more user-centric than the TCO standard measurement and should be employed in a future standardisation.
