Abstract:
A new type of photonic crystal structural colored fiber was prepared by assembling superparamagnetic chains on the surface of a flexible fiber in a magnetic field under photopolymerization. In this system, fixed structural colors (blue, green, and red) were generated instantaneously. The fiber with multi-stopband can also be prepared by carefully controlling the size of the magnetic spheres in each photopolymerization procedure. This method would be fast and facile for the further study of structural color on the surface of the fiber, and the process may be used to simulate the conventional fiber coloration process.

Magnetic Field Due To A Thin Straight Wire
Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
