A car tyre is normally threaded with wire loops. Dunlop tyres have about 200 loops a tyre. A car running on such tyres travels at speed of 16.7 m s−1 along a level road such that the magnetic field of the earth makes an angle of 53° with the axis of the tyre at all the times. If the magnetic field is 1.02×10−5 T, calculate (i) The induced current through a loop if the tyre’s diameter is 0.65 m and its resistance per unit length is 8.0×10−3 Ω m−1. (ii) How much power is generated on the tyre due to its motion in the earth’s magnetic field? (iii) What does it suggest to you about the usage of threaded car tyres?

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.
