Calculation of self and mutual inductances

[P.Neumaier@xxxxxxxx]

Hello,

can anybody help me? When I calculate the self inductance of e.g. a 
coil encircling a copper rod using the "A.J" integral I get the 
correct unit "Henry * A²". But this integral yields incorrect 
results, which can be prooved when defining a problem, which can also 
be solved analytically. However, using the integral "A" for the 
mutual inductance, the value is correct, but the unit is given 
as "A*m³" which is obviously not the unit for an inductance.

Thanks for any answer in advance.

Peter
