✦ Synopsis

The connection between the magnetic field geometry and the thermal properties of solar coronal structures is investigated. Gravitational effects, that can modify the spatial dependence of the thermodynamical quantities, but have no influence on the plasma-field interaction, are omitted to simplify the problem. A series of two-dimensional models is constructed, in which a strong coupling between the magnetic field shear and the thermal structure of the loop is clearly pointed out.

It is shown how it is possible to deduce detailed information on the small scale magnetic structure by the use of measurement of purely thermodynamieal quantities. Similarly information on the spatial dependence of the energy deposition function can also be obtained.
