If I have a LUKS encrypted partition with a passphrase, is all the information to unlock the partition contained in the header?

Is the following correct:

The passphrase allows access to the header which contains the key that the partition was encrypted with? And if I move the entire partition to another system, and have the passphrase, will I be able to mount?

Yes. That is correct. A LUKS volume is self contained and works as you described.
