... field, you would call it a “motional emf”. For example, if a loop moves into or out of a region of field, or rotates, or a bar rolls along a rail, you’d get a “motional” induced emf. But if the changing magnetic flux were due to, say, an increasing current in a wire, you wouldn’t call it a “motional ...

However, the large wire loop only covers a limited fraction of space, and therefore definitely will not intercept all field lines outside the square loop. Ther ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
