I do not see much too strange about this. Consider the force on a
current loop to be F=qVXB (note X is the cross product of vector
quantites V and B) and you see via the right hand rule that there is a
force on a current loop if the loop is angled wrt the field direction.
Yes, the force is small which would explain why they discuss small
satellites and the right hand rule might explain the weird reference
to "tornado motion" and would explain why they use a battery (to
provide current).


Yeah, but they say that this somehow involves gas or liquid, not just
electricity.
Anyway, it's from Pravda ("Where The Truth Hurts") which has many
"interesting" science articles, like Martian life coming from Earth soil
that was tossed into space during the Biblical Flood:
