In the figure below, two concentric circular loops of wire carrying current in the same direction lie in the same plane. Loop 1 has a radius 1.50 cm and carries 3.50 mA. Loop 2 has a radius 2.50 cm and carries 6.40 mA. Loop 2 is to be rotated about a diameter while the net magnetic field B(vector) set up by the two loops at their common center is measured. Through what angle must loop 2 be rotated so that the magnitude of that net field is 100 nT? _______________° (please show units. It really helps me out)

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.
