is there a way to block a magnet field without any repulsion between the magnetic object and the object blocking its field?

A static field will eventually "soak" through any material except a superconductor. A magnetic field needs time to penetrate a metal depending on the metal's resistivity and the freguency of the oscillation. Since a superconductor has no resistance the field can never penetrate it. You've probably seen pictures of a magnet levitating over a superconductor. It also demonstrates that the force of mutual repulsion is proportional to the amount of shielding (blocking).

Yes . Magnetic field can travel in a circuit . If the filed is envelopped with a sheet metal of iron ,the field would remain contained in the matereial and would no longer permeate externally.

I think you can use grounded shielding.
