There are two straight arrays above the plasma column, each with 12 coils, mounted in a 0.5 mm thick stainless steel tube attached to a port flange. The 12 coils are distributed in 4 groups of 3 coils each, separated by a distance of 30 mm. The three coils in each group measure the three cylindrical components (''R'', ''φ'', and ''Z'') of the magnetic field. | There are two straight arrays above the plasma column, each with 12 coils, mounted in a 0.5 mm thick stainless steel tube attached to a port flange.

* One straight array in [[TJ-II:Sectors|sector]] B5, at ''φ'' = 232°. The corresponding signals in the [[TJ-II:Shot database|TJ-II database]] are called 'MIB5xy', where 'x' is 'R', 'F' (φ), or 'Z', and 'y' is the coil number. | * One straight array in [[TJ-II:Sectors|sector]] B5, at ''φ'' = 232°.
