Electric and Magnetic Fields

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?

Solution Preview

From the treatment of Electric and Magnetic fields, we can arrive at the following generic results :

Energy density (energy per unit volume) for magnetic ...

Solution Summary

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.
