Carbon Nanotube (IMAGE) University of Gothenburg Caption A suspended carbon nanotube can be made to vibrate like a guitar string. Gustav Sonne has studied how these oscillations influence the properties of the system if a magnetic field (H) is used to couple the mechanical motion of the tube to the electric current through it.
