Homework Help: Magnetic Tubular Capacitor

  1. Feb 2, 2012 #1
    Hy.

    I'm an amateur scientific. This is my first post. Sorry if this is not the right place. Let me know & I'll change it immediately, but as far as I have seen, this is where I consider more appropriate.

    I have a copper tube, with a thick plastic strip wrapped over, between an aluminum strip wrapped over the plastic strip. That's a tubular capacitor, with the plastic acting as the dielectric, one plate is inside copper tube, the other plate is the aluminum strip. If I charge this tubular capacitor using a sinusoidal Voltage, what kind of magnetic field will generate inside the dielectric & outside the capacitor?

    Same question but now, I have two circular plates like this.

    If the magnetic field is ;

    This means that the magnetic field goes perpendicular to the Electric Field like this? Is that correct?

    I know that it is a little bit bizarre my questions, but It's a idea for a special motor, for pedagogical purposes.

    Thanks.
