How do we detect the magnetic north in a solenoid?

Expert Answer:

Dear student,
A solenoid becomes a magnet when current flows through it and the field lines are quite similar to the ones like in a bar magent. If a bar magnet is allowed to rotate freely, one end will point towards the geographic north, and the other end towards geographic south. The end that points towards geographic north is the magnet's north pole, hence you can determine the solnoid's north by this method.
Hope this helps.
