lbe something as shown in Fig. 371.The effect is much the same as thatproduced on a magnetic field bybringing a bar of iron into it.The lines of force are more crowdedthrough the non-conductor thanformerly through the space nowoccupied by it. 592. Zero Potential of the Earth. On account of the… … Fig. 371. 5IO ELECTRICITY AND MAGNETISM. calculate potentials from that of the earth assumed as zero. Sinceany two conductors joined together by a conducting medium, asa wire for example, are quickly brought to the same potential,any conductor joined to the earth has its potential brought tozero.…
