  We report the fabrication of small (Ba,A)Fe2As2 (A: Na, K) coils using 10
m-class long round wires, fabricated by powder-in-tube (PIT) method. Coils are
sintered using hot-isostatic-press (HIP) technique after glass-fiber
insulations are installed. Critical current (Ic) of the whole coil using
(Ba,Na)Fe2As2 and (Ba,K)Fe2As2 are 60 A and 66 A under the self-field, and the
generated magnetic fields at the center of the coil reach 2.6 kOe and 2.5 kOe,
respectively. Furthermore, the largest transport critical current density (Jc)
and Ic in (Ba,Na)Fe2As2 wires picked up from the coil reach 54 kAcm-2 and 51.8
A at T = 4.2 K under a magnetic field of 100 kOe, respectively. This value
exceeds transport Jc of all previous iron-based superconducting round wires.
Texturing of grains in the core of the wire due to the improvement of the wire
drawing process plays a key role for the enhancement of Jc.
