A solenoid used in magnetic resonance imaging ("MRI") has to be large enough for a human being to fit inside the solenoid cylinder, where there is a strong, uniform magnetic field produced. One such solenoid is wound from lots of adjacent turns of a single layer of (niobium-titanium) superconducting wire 2mm in diameter. Using the approximate size of a human, estimate relevant parameters about the solenoid, and use them to estimate the self-inductance of this solenoid.

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.
