two parallel conductors are located one above the other, with both carrying currents in opposite directions. As a result they repel each other. is the upper conductor in a stable state of levitation?

Question

b) Now we reverse one current so that the two conductors attract each other. Is the lower conductor in a stable state of levitation?

..ive gone over all my notes and im still confused about this question...i don't really understand what is meant by a stable state of levitation and how that would differ from the upper and lower conductors...any help would be great.

Answer 1

I assume stable means force of attraction/repulsion = weight of cable.

It would take quite a current to do that.
