Induced current () it is only in a closed circuit its value is i e n do r r dt it does not depend on change in time.

Induced current () It is only in a closed circuit Its value is i e N do R R dt It does not depend on change in time. how it possible that induced current is independent of time at all time . it is not genral statement

    yeah, for sure , the statement in the question is not general. it is true if glux is linear in time(i.e. proportional to first power of t ). otherwise it will depend on time. Best regards.

    induces current Changes with change in magnetic flux but induce charge doesn't depend on change in flux.

    please explain that if charge is not changed than how it is possible to change current

    when flux changes, charge is induce and there start moving due to this induce Current generate.. with time, induce current change because with time flux change and due to this motion of induce charge changes means current increase.. means induce current depends on the no of induce charges and also in its motion...

    so if charge is not change but there motion change then current change , also u can see I=neAv so I not only depend on e but also on v

    thanks I understand .

    the induced current we are talking here seems to be due to change in magnetic flux . As far as I know ,there is no current which is independent of time . I think induced Charges are independent of time, not the current.so yes you are right ,this is not a general statement at all .To support my answer ,I am attaching a question.free feel to ask doubts.

    yes mam but I have another dobut that if induced current is changes when time changes and mathematical we see that induced charge is not change with time . how can induced current changes if no. of charges not changed.
