Hey guys, in order to understand electromagnetic induction I have been pondering a hypothetical question.
This may sound quite silly but here goes:
If a coil were emersed in a UNIFORM magnetic field, i.e. the magnitude and direction of the magnetic field were exactly the same at all points around the coil, with the hollow of the coil orientated to be in the same direction of the magnetic field. If the magnetic flux density of this field were made to change in density (but still keep its uniformity) is it possible that there will be an induced emf in the coil?
Naturally, if a magnet were moved toward a solenoid, a potential will be created but my question replaces the magnet with a completely uniform field.
My instinct is to say that no, no induction will occur...
Could somone give me substantiated answer to this question?
