    WEBThe toroid is a useful device used in everything from tape heads to tokamaks. Magnetic field = permeability x turn density x current. For a solenoid of radius r = m with N = turns, the turn density is n=N/ (2πr) = turns/m. If the current in the solenoid is I = amperes. and the relative permeability of the core is k = ,

    WEBThe terms toroidal and poloidal refer to directions relative to a torus of reference. They describe a three-dimensional coordinate system in which the poloidal direction follows a small circular ring around the surface, while the toroidal direction follows a large circular ring around the torus, encircling the central void.
