Superconductivity and carbon nanotubes, are Type I, while almost all impure and compound superconductors are Type II. Conversely, a spinning superconductor generates a magnetic field, precisely aligned with the spin axis. The effect, the London moment, was put to good use in Gravity Probe B. This experiment measured the magnetic fields of four superconducting gyroscopes to determine their spin axes. This was critical to the experiment since it is one of the few ways to accurately determine the spin axis of an otherwise featureless sphere. Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance
Heike Hanada have to be made concerning what is to be demolished and how one can or should adapt oneself when building. It is a tricky balancing act in which conservative conclusions come easily. When a new building stands next to an old one, the difference in periods is made articulate, the new enriches the old and vice versa, resulting in a powerful wholeness. The extension has officially been put on hold in autumn 2009 after a change in local government and a massive campaign about what critics saw as an unacceptable impact on the original, Asplund approved complex.
