A conducting sheet lies in a plane perpendicular to a magnetic field B → that is below the sheet. If B → oscillates at a high frequency and the conductor is made of a material of low resistivity, the region above the sheet is effectively shielded from B → . Explain why. Will the conductor shield this region from static magnetic fields?
