The diagram below depicts a rectangular wire loop of width a = 17.5 cm and height b = 7.95 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.35 A in the wire. The loop is suspended in a uniform magnetic field B = 0.85 T that points in a vertical direction as shown in the diagram, and it would hang vertically if there were no current in the wire. We assume that the wire is massless, but two masses m = 9 g are suspended at the lower corners. What is the angle, θ, at which the loop is in equilibrium?

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.
