A magnetic field has a magnitude of 12 T. What is the magnitude of an electric field that stores the same energy per unit volume as this magnetic field?© BrainMass Inc. brainmass.com March 4, 2021, 5:52 pm ad1c9bdddf
From the treatment of Electric and Magnetic fields, we can arrive at the following generic results :
Energy density (energy per unit volume) for magnetic ...
Energy density (energy per unit volume) for magnetic field, n_b = 1/2 * B^2/u. Energy density (energy per unit volume) for electric field, n_e = 1/2 * eps*E^2. See solution for full calculations and answer.
