The magnetic field of a proton is approximately like that of a circular current loop 0.650 × 10-15 m in radius carrying 1.05 × 104 A. An MRI machine is required to be able to manipulate these fields.  Part (a)  To see why an MRI utilizes iron to increase the magnetic field produced by a coil, calculate the current required in a 400 loop-per-meter circular coil 0.660 m in radius to produce a 1.20 T field (typical of an MRI instrument) at its center with no iron insert.  Part (b)  What is the field at the center of a proton? Notice how it compares to the field we used in the previous calculation.

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.
