Energy stored in magnetic fields
WebMar 25, 2015 · it can be said that the, energy stored in the the inductor is due to the temporary alignment of these dipoles. but few magnetic dipoles can not attain their initial configuration. hence, we say pure inductor is not present practically. Scientists know that the electric fields and magnetic fields are co-related. This was first confirmed by ... WebStrategy. The magnetic field both inside and outside the coaxial cable is determined by Ampère’s law. Based on this magnetic field, we can use Equation 14.22 to calculate the energy density of the magnetic field. The magnetic energy is calculated by an integral of the magnetic energy density times the differential volume over the cylindrical shell.
