Does the magnetic field produced by a magnet act on itself?

[Poopypoop123]

So when a conductor in complete circuit is placed next to a moving magnetic field, current in the conductor is induced and the induced current again produces its own magnetic field. So does this new magnetic field act on the conductor? It's the same as the question in the title. Is my concept wrong? I'm really confused.
Thanks a lot for the help!

Yes. Or, more precisely, the magnetic field from one part of the conductor will act on other parts of the conductor. If you have a conductor loop made out of a very flexible material and power it, it will try to reach a circular shape due to this interaction.

The backreaction from the coil's magnetic field to the conductor that you discuss is also present, and it is the idea behind eddy-current brakes for example: A moving magnet induces currents, those currents induce a magnetic field that slows down the magnet.

OK thanks.

One more question. When a bar magnet is dropped through a conducting ring,current is induced. Is there current induced when the ring is perfecting in the middle of the bar magnet? And why?

No matter how you place it, you'll always have places where the magnetic field strength changes, which induces a current.
