This study addresses the problem of magnetic field emission produced by the laptop computers. Although, the magnetic field is spread over the entire frequency spectrum, the most dangerous part of it to the laptop users is the frequency range from 50 to 500 Hz, commonly called the extremely low frequency magnetic field. In this frequency region the magnetic field is characterized by high peak values. To examine the influence of laptop’s magnetic field emission in the office, a specific experiment is proposed. It includes the measurement of the magnetic field at six laptop’s positions, which are in close contact to its user. The results obtained from ten different laptop computers show the extremely high emission at some positions, which are dependent on the power dissipation or bad ergonomics. Eventually, the experiment extracts these dangerous positions of magnetic field emission and suggests possible solutions.
Mapowanie globalnej aktywność burzowej w skalach czasowych od minut aż do wielu lat, co odgrywa ważną rolę w pomiarach i prognozowaniu efektu cieplarnianego. Weryfikacja modeli wpływu różnych form aktywności Słońca na stan dolnych warstw jonosfery. To m.in. umożliwia na Ziemi system WERA. Kiedy przyjdzie czas, sprawdzi się także na Marsie.
Mapping storm activity across the globe at time scales ranging from minutes to years is an important element of measuring and forecasting climate change. The WERA system is being used to verify models of the influence of various types of solar activity on the lower layers of the ionosphere. We hope that one day it can also be used on Mars.
