Magnetism

Magnetism and applications is studied by Eija Tanskanen group that is part of the Department of Electronics and Nanoengineering, Aalto University. The main research topic is the magnetic environment on ground, near-Earth space, moon and solar surface. Magnetic disturbances vary in time-scales from seconds and minutes to seasons and solar cycles (11- and 22-years). The magnetic environment is monitored by magnetometers which data is used to detect auroral substorms and their seasonal pattern, Pc5 pulsations, Alfvénic fluctuations embedded to fast solar wind, solar surface magnetic field topology, coronal hole morphology and stellar variability. The group is located in the second floor of the TUAS building.
Magnetism

We live in an electromagnetic world almost without noticing the forces that have an influence on us, on our environment and on the basic functions of our society. Our lives and homes are filled with devices, used every day, which are based on magnetic forces including cars, computers, microwave ovens, credit cards and cell phones. Research of magnetism has a long history starting over 4000 years ago when compass was invented for orientation purposes. Scientific quality geomagnetic data has been recorded in Finland since 1844 and high-quality magnetometers have been build in Aalto University (then Helsinki University of Technology) already in 1950´s. Nowadays wide variety of magnetic data is available from ground and space instruments which can be used to study how magnetic forces act in spatial scales from nanometers to light years and time-scales from seconds to solar cycles. Large magnetic disturbances affect critical infrastructure and functions such as telecommunication, aviation, electricity, energy and water supply as well as navigation.
