One example is a shielded cable, which has electromagnetic shielding in the form of a wire mesh surrounding an inner core conductor. The shielding impedes the escape of a… See more

Electromagnetic radiation consists of coupled electric and magnetic fields. The electric field produces forces on the charge carriers (i.e., electrons) within the conductor. … See more

Equipment sometimes requires isolation from external magnetic fields. For static or slowly varying magnetic fields (below about 100 kHz) the Faraday shielding described above is in… See more

Suppose that we have a spherical shell of a (linear and isotropic) diamagnetic material with relative permeability μ r {\displaystyle \mu _{\text{r}}} , with inner radius a {\displaysty… See more
