Re: [Phys-l] induced emf and induced current



Hmmm... this seems to conflict with the concept I had in mind when considering a pigeon's wing moving wrt the geomagnetic field, long ago.
No electric circuit - but displacement current, I supposed.

But recall that Faraday dangled electrodes from a bridge across the Thames, expecting (unsuccessfully as it turned out) to see the potential due to the river current.

I'm not sure what is meant by "the induced emf could be considered as towards the centre". The induced emf, as I understand it, is the result of integrating the induced electric field around a closed path encompassing a changing magnetic field. It doesn't really exist from point to point because magnetic flux cannot be defined relative to an open path.
