Magnetic needle inside a solenoid

[Entanglement]

What will happen If I place a magnetic needle inside a solenoid, I mean will the South Pole of the needle be directed towards the South Pole of the solenoid since it is north from inside and the same way regarding the North Pole

Right.

Right.

Thanks !

Right.

So If I want to change the compass direction by 180 degrees should I place the compass in a solenoid that's North Pole is towards the geographic South Pole of the Earth and the south of the solenoid towards the Geographic North Pole of the Earth ?

That is possible (assuming the field of the coil is strong enough), but why would you want to change the direction of a compass needle like that?

That's a problem that I was solving I am making sure my answer is right

Thanks a lot !
