When is the flux through a coil from a bar magnet zero?

[QUOTE="Cutter Ketch, post: 6305439, member: 515910"] Lines of magnetic flux form closed loops. That is to say, the flux inside the bar magnet is not zero. There is a very strong B field pointing the opposite direction from the more accessible parts of the loops outside the bar. So unless your loop of wire is very large extending out to where the magnetic field is almost zero, the flux through your wire is not anything like zero even in the static case. Unless it is moving close to the speed of light, the movement of the bar doesn’t change the snapshot of the magnetic field of the bar magnet at that moment when the bar is in the middle. [/QUOTE]
