Synopsis: One-Way Transfer of Magnetic Fields - Physics

The answer, they found, is yes, if both coils are placed in between the two walls of a hollow, rotating, conducting cylinder, where the walls have a U-shaped cross section. In calculations and a proof-of-principle demonstration, Prat-Camps and colleagues showed that when the cylinder rotates at a constant velocity, a magnetic field from coil A can transfer to coil B, for example, but not the ...

Magnetic field of rotating cylinder | Physics Forums

2007-12-12· The problem is to find the magnetic field within a rotating cylinder (infinitely long) that has on its surface a given surface charge density p. I made a picture of the problem to illustrate this. The only hint given: "the magnetic field outside the cylinder is zero. Well, to be cleary, I can solve

The Field near an Infinite Cylinder

The analagous situation for Ampere's Law is a long cylindrical shell carrying a uniformly-distributed current I. Inside the hollow part of the cylinder the magnetic field is zero (an amperian loop encloses no current) and outside the cylinder the magnetic field is the same as that from a long straight wire placed on the axis of the cylinder:
