What could you put between a magnet to stop it from pulling on an iron material?

I'm talking about the name of a specific material!

A sheet of low-coercivity ferromagnetic material, like soft iron. Magnetic disks are often kept in iron boxes to prevent stray magnetic fields corrupting the data on them.

Not much. Putting a sheet of something with a higher permeability between the magnet and the ferromagnetic material would reduce the field strength some, but it wouldn't completely reduce the field effect.

You can take an equal magnet and reverse polar it to the opposide of the sheet and force off the magnet directly. from the steel sheet. That is a common practice used in rollers which operate in a reclaim facility on trash where steel cans and the like are reclaimed with perm magnets.

The magnetic field is dependant on distance. Putting something in between will not cancel the magnetic field.

the only fabric which will thoroughly shelter a magnetic field is a superconductor - its called the Meisner result. Its not stressful to acquire superconducting components, even regardless of the indisputable fact that it fairly is stressful to get them chilly sufficient to superconduct.
