Energy Density of the a Magnetic Field

“Live as if you were to die tomorrow. Learn as if you were to live forever.” 

    • From analysis of the energy stored in a conductor,



    • The energy density(energy/volume) is:

    • So the energy density stored in the magnetic field is:

    • This equation gives density of stored energy at any point where the magnitude of the magnetic field is B.

    • The energy density in a vacuum:
