Unformatted text preview: both B and E simultaneously. 6) Explain what symmetry conditions must apply to a static current distribution in order for Ampres integral law to be useful in practice. 7) Define what an Amperian path is. 8) Explain the meaning of the basic types of current densities: a. Volume J b. Surface J s c. Line i 9) Explain the nature (field components and their spatial variation) of magnetic fields produced by circular cylindrical (axisymmetric) static current distributions. 10) Apply Ampres law to the case of an infinitely long, thin, straight wire carrying a static current i ....
