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.

Part A
An MRI scanner is based on a solenoid magnet that produces a large magnetic field. The magnetic field doesn't stop at the solenoid's edge, however, but extends into the area around the magnet. Suppose a technician walks toward the scanner at 0.80 m/s from a region
1.0 m from the scanner where the magnetic field is negligible, into a region next to the scanner where the field is 4.0 T and points horizontally.
As a result of this motion, what is the maximum magnitude of the change in flux through a loop defined by the outside of the technician's head? Assume the loop is vertical and has a circular cross section with a diameter of 15 cm.

Mass spectrometers like the one in the figure are ingenious devices that use electric and magnetic fields to separate and/or identify ions based on their specific charge-to-mass ratio, q/m. Steering Region. The magnetic force exerted on the ions is centripetal so move along a circle. The radius of a given ion's circular path is directly proportional to its charge-to-mass ratio. Velocity Selector. In order to reach the steering region, the ions have to pass through the crossed E and B fields between the plates of the velocity selector -- without being deflected. The last bit of the puzzle is the detector. In order for the ions to enter the detector, it must be located one diameter to the right of the point where the ions entered the steering region. Write a symbolic expression for the charge-to-mass ratio of the collected ions in terms of B, E, and r (ONLY) then calculate its numeric value.
