Can a solenoid be used to find the direction of earth's magnetic field ( magnetic North and magnetic south)?

A solenoid is a cylindrical/helical coil whose length is more than its diameter. When we pass current through the solenoid , a magnetic field is set up in the space around the solenoid similar to that of a bar magnet.
There is ,in fact, a strong and uniform field in the core of the solenoid.At the two ends of the solenoid, poles are developed as in a bar magnet.
So the current carrying solenoid if freely can show the direction of the magnetic field of a magnet.The north end of the magnet shows the geographic north and South end shows south .
