Is the loss of silicon steel measured under sinusoidal magnetic field or measured under a constant magnetic field?
Direct current produces a magnetic field. Because the electrons are in transition, electrons constantly collide with neighboring magnetic fields, so that the adjacent magnetic fields constantly diffuse the energy of the impact.
Note that this energy diffusion, like the pendulum back and forth that kinetic energy potential energy, electric energy, magnetic energy is spread back and forth diffusion does not consume energy, but farther away, the greater the three-dimensional diffusion surface, to be carved up by the more powerful, until the energy is less than the magnetic particle partition of inertia so far. The magnetic field produced by a direct current cannot be said to be constant, nor can it be changed, but the state remains the same.
