Smok Nord 50w are press fit, I do not believe they are magnetized. I have 4 of them (and multiple tanks, various coils, etc). The only time I have had a problem is the LP2 tank not fitting into one device. Then, it falls off. The connections do not fit the bottom of that tank and coil head. I use that battery for Nord tanks.
If you only have one, then exchange it. Methinks they made a mistake in the manufacture sometimes, and it was meant for only Nord pods and not LP2. Also, watch a few you tube videos, to make sure you have the pod in right.
