Two parallel wires are separated by a distance of 0.05 m. Wire 1 (located at the left) carries a current of 12.0 A. Wire 2 (located at the right) carries a current of 6.0 A flowing in the opposite direction. Find the (a) magnitude and direction of the magnetic field created by wire 1 at wire 2, (b) force exerted by wire 1 on the 2.0 m long section of wire 2, and (c) force exerted by wire 2 on wire 1 if current 1 is going up and current 2 is going down. Find the (a) magnitude and direction of the magnetic field created by wire 1 at wire 2, (b) force exerted by wire 1 on the 2.0 m long section of wire 2, and (c) force exerted by wire 2 on wire 1 if both currents are going up.

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.
