electrcity in another way

If I understand your question correctly, you can induce an emf across the coil with an unchanging magnetic flux if you change the orientation of the coil within that flux. So the flux with respect to the earth is not changing, but it is changing with respect to the coil. A lot of generators work this way.

Also, changing the current through the coil results in an emf, but this is because the change in current is causing a change in the coil-induced magnetic flux. So that kind of negates the conditions you stated in your question.

Dear peter:

The short answer is no. If there is no EMF induced by the magnetic field, and you are not otherwise driving current through the coils, it doesn't matter how you connect an external circuit up to the coil. No EMF is no EMF.

Hmmm...the crunch is in the descriptor "when the terminals change."

If the terminals change, you still need to measure the terminal voltage, so the meter leads change, so the area in the loop MAY change??
