A current carrying coil produces magnetic field around it.  Field lines in the form of circular loops of magnetic field with wire at it center is produced. Right hand thumb rule can be used to find the direction of the magnetic field. The thumb points in the direction of the current, the fingers curl in the direction of the magnetic field.
