* 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'', ''Z'', and ''&phi;'') of the magnetic field. They are located in [[TJ-II:Sectors|sectors]] B5 and C4, at ''&phi;'' = 232&deg; and 308&deg;. The signals in the [[TJ-II:Shot database|TJ-II database]] corresponding to the B5 coils are called 'MIB5xy', where 'x' is 'R', 'F' (&phi;), or 'Z', and 'y' is the coil number.

* One straight array in [[TJ-II:Sectors|sector]] C4, at ''&phi;'' = 308&deg;.  
* One poloidal array with 15 coils measuring the poloidal field component. This array is located between [[TJ-II:Sectors|sectors]] D4 and D5, at ''&phi;'' = 45&deg;. The signals in the [[TJ-II:Shot database|TJ-II database]] corresponding to these coils are called 'MID5Px', where 'x' is the coil number.
