Hi All,

Please show me the derivation of the vector potentiol A for the magnetic dipole.
from equation 8.21 to 8.21a

** i tried all day and couldnt manage to obtain it. i need the derivation step by step **

It looks like the cosine law in a triangle.You should spot that triangle out from the drawing (check all slides).

And the magnetic potential is the solution of Poisson equation for magnetostatcs.
