Picture a square coil of thin wire, with 153 turns.  It lies flat on a table, where there is a strong 0.85-Tesla magnetic field.  Each side of this square coil is 9.1-cm long, and it has a 6.5-Amp current running through it.  You're doing an experiment on torque, and you need the loop to experience a torque with a magnitude of exactly 1.1 m*N.  At what angle above the table (see the figure) should you apply the magnetic field to achieve this (magnitude) torque? The angle =  _________ degrees. Give 3 significant figures, and enter a positive angle, less than 90 degrees.

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.
