Abstract
We have developed a trap of a single superconducting micro-particle using a quadrupole magnetic field in superfluid helium. By displacing the particle from a stable static position and then releasing it, the particle was observed to oscillate around the stable position. Analyzing the damped oscillation, we have demonstrated the measurement of the viscosity of superfluid helium.
