No. Or rather, it's a lot more complicated than that. Magnets are important in a cathode ray tube style television, but they don't "make the picture". The picture shows up as a result of an electron beam hitting the phosphor-covered inside of the tube. The magnets are used to steer the electron beam. In an LCD or LED type television, there are no magnets and an entirely different process is used.

four coils are used to create a magnetic field to deflect the electron beam in two dimensions.
A tube pan is usually a round pan, with a tube in the center. Generally they are used to make angel food cakes, but I'm sure they can be used for other cakes. the one below is fluted but they come smooth also.
