The door to my office is 0.88 m wide and 2.39 m high, with an aluminum frame around the very edge.With the door open, as shown, it faces to the north.  (That is, if I stand with my back to the door, I am looking north.)  Since the earth's magnetic field equals 5.0 x 10-5 T and points to the north, what flux, if any, is caught by the open door?  Express your answer to two significant figures in exponential notation.

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.
