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 ondo drums and the taru barrel in his or her ensemble, in intricate drumming techniques. Heike Ondo is accompanied by a kind of shamisen called the Heike Shamisen, which has a shorter neck than most shamisens in Japan, and thus, a higher range. The narrative is quite long and is rarely ever sung in its entirety; key excerpts are chosen for shorter performances. The song is sung by a main singer accompanied by a group of singers who know when to call out the kakegoe (see below). The dance that accompanies Heike Ondo is called Heike Odori (平家踊り). It is simple
