โฆ Synopsis
A solenoid magnet has been constructed with a new anode oxided aluminium stabilized Nb Ti wire, in which AI and Nb Ti are directly bonded. An average current density of 16800A cm -2 at 49 kG was obtained. With this new developed drawing technique, duralumin can be applied on the exterior as reinforcement, if needed. Now the construction of light-weight and high current density superconducting coils is possible for air-borne magnets, suspension magnets etc.

When a superconductor switches from a superconducting to a normal state, the current will move out of the superconductor and redistribute itself in the stabilizer. To study this current diffusion phenomenon in the conductor, a separation of variables method is used to solve directly the current diff

The effect of time delays occurring in the feedback control loop on the linear stability of a simple magnetic bearing system is investigated by analyzing the associated characteristic transcendental equation. It is found that a Hopf bifurcation can take place when time delays pass certain values. Th
