  With the advances in the optimization of magnetic field equilibria,
stellarators have become a serious alternative to the tokamak, bringing this
concept to the forefront of the pursuit of fusion energy. In order to be
successful in experimentally demonstrating the viability of optimized
stellarators, we must overcome any potential hurdles in the construction of its
electromagnetic coils. Finding cost-effective ways of increasing the number of
operating optimized stellarators could be key in cementing this magnetic
confinement concept as a contender for a reactor. In this work, an alternative
to modular coils, permanent magnets, are studied and are shown to enable the
possibility of converting a tokamak into a stellarator. This is then applied to
the case of ISTTOK tokamak, where an engineering design study is conducted.
