The production and maintenance of an internal magnetic field in a compact space is a challenging
problem, and a versatile solution is being pursued. This is based on the property of a bulk hollow
superconductor to trap a magnetic field inside it, that is very interesting for fundamental physics
and industrial applications too. Our goals are to provide an intense magnetic field in a small
region. Compactness, transportability, no power connections, capability of maintaining a high
magnetic field and shielding surrounding magnetic fields are the most attracting characteristics of
a MgB$_2$ bulk. A preliminary feasibility study on a test cylinder showed very promising results.
We are upgrading the system for better controls and systematic studies of the required material
and geometry for application in transverse polarized nuclear targets for fundamental physics
investigations, and for the proposal of polarized nuclear fuel for test in fusion facilities.
