Essential Eddy viscosity and Von Karman constant using mixing-length theory.
Using the mixing-length theory, identify:
1. Eddy viscosity
2. Von Karman constant.
Determining the magnetic field magnitude and direction at the center of loops.
A current of 2.5 A runs through 20 circular wire loops of diameter 10 cm. What is the magnetic field magnitude and direction at the center of the loops? (Illustrate the derivation of any formula that you use.)
