Question

You need to find the self-inductance of a complex, winding trace on a circuit board. You could: Calculate the local magnetic energy density for a given amount of current I, integrate it over the volume to get the total magnetic energy, then solve for L using Total Magnetic Energy = 1/2 Ll^2 Propose a current I. figure out the resulting magnetic field B. then use the definition of inductance. L = (integral B* dS)/1, where S is the surface bounded by the trace, (here the number of turns N = 1). Do either a or b Nothing, because inductance has no meaning for something that is not a circular loop or a coil.

Explanation / Answer

c)

Both 'a' and 'b' can be used.
