I need to shield a magnet but the magnet can not be attracted to that material
It needs to shield a permanent magnet not an EMF.
Any suggestions?

If you don't mind the material repelling the magnet, an superconductor is a perfect magnetic shield.

All Diamagnetic Material will be non permeable magnetic material. You can also take a superconductor as an example. At below curie temperature the superconductor material will behave as diamagnetic which will not allow magnetic fiels to get or pass thro it Next is wood, paper etc. they are also diamagnetic when their thichness increases it doesnot allow magnetic field, Any material with higher thickness will not allow magnetic field to enter thro it completely The strenght of magnetic field will decrease propotionally to the increase in the thickness of the material Iron is permeable but can shield magnetic field that is it can by-pass the magnetic field so that there will be a very lower or no field beyong any iron sheet. But if measured in iron, it have the field

a lot are. when you construct a cage with materials such as copper wire or such you shall have built a faraday cage
