Among the observational astronomers it is quite customary to assume potential magnetic fields in calculating the strength and the direction of the magnetic fields on the stellar surface. People use this assumption because

  1. 1. it is easy to calculate,

  2. 2. it is possible to fit the observations with the calculations to some extent using the parameters inherent to the model,

  3. 3. at a first glance, there is no difficulty in assuming both potential magnetic fields and static stellar atmosphere because they do not interact each other (except at the pole).
