The magnetic field can store energy, but it can do no work. Therefore, another agency must be responsible for doing the work that puts the energy into the magnetic field. In order for the energy in the field to be reduced to zero, work must be done. Explain where the energy goes when the B field collapses. What possible agency (or agencies) might be doing the work? Discuss in terms of Maxwell's equations.© BrainMass Inc. brainmass.com March 5, 2021, 12:34 am ad1c9bdddf

In this solution we explain why work is required to reduce the magnetic field in a given region.
