Is it possible to have a flux of 0.5 Wb in a magnetic circuit without having a flux density of 0.5 T? Is energy required to maintain a steady magnetic field after it has been established? When a steady current through a coil can establish a certain magnetic field, why do we need the permanent magnets?
