In both of these examples, the conductor has magnetic flux lines cutting and traveling through it. In a generator, the stator is usually constructed with teeth holding the coils. These teeth focus and channel the flux, so that ... Web7 okt. 2024 · So, no electric field will be produced. The charge of the wire being zero means that there is no electrostatic E-field. However there are other ways to produce E fields. Faraday’s law says $$\nabla \times E=-\frac{\partial}{\partial t}B$$ Which means that you can also get a circulating E field by having a B field which changes in time.
