ducting circuit be moved acrossa magnetic field without having a current induced therein? Ans. If a conducting circuit—a wire ring or single coil, forexample—be moved in a uniform magnetic field, as shown in fig.127, so that only the same number of lines of force pass throughit, no current will be… … Fig. 127.—Electromagnetic induction: In order to induce a current by electromagneticinduction, a conductor must be so moved through a. magnetic field that the number oflines of force -passing through it (that is, embraced) are altered. If a coil be given a simplemotion of translation in a uniform…
