(a) what radius (in m) circular path does an electron travel iIf it moves at 8.00 x 10* m/s perpendicular to a magnetic field of 0.920 T? (b) what is the angle between a wire carrying an 8.10 A current and the 1.20 T field it is in, if 50.0 cm of the wire experiences a magnetic force of 2.25 N? (c) Two leng wires (1 and 2) run parallel to each other with wire 1 suspended directly above wire 2. The wires (1 and 2) respectively carry currents of !, - 22.0 A and !;- 67.0 A and they both have a weight per unit length of 0.088 N/m. Determine the distance that wire 1 should be mounted above wire 2 in order for it to be held in place by magnetic repulsion.

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.
