Answer:
like the user above me said you would violate the first law of thermodynamics which is energy cannot be created or destroyed, only transfered/transformed. also it's not the magnetic field itself that produces electricity, it's the variation of it that does, so you'd still had to use some kind of energy to acomplish that.
