Hi all, I have a small system which has a magnetic field and I don't want it to be interfered by the external magnetic field around it. I've read some document about this. And what I've got is that in case of a variable magnetic field, I should place a conductive plate on one side of the printed circuit board to reduce the effect of the external magnetic field based on the Eddy current. If the magnetic is static, I should use permeable material, which has the ability of re-routing the external magnetic lines, to cover my system completely. However, I don't want my system covered. So could you tell me some other potential solutions ? Thanks.
