A 2.5 cm-long horizontal wire segment has mass 0.15 g and carries a current sufficiently large that it levitates when the segment is in a region of B field upward with magnitude 1.5 T. The current is passed to the segment that is in the magnetic field by way of massless electrical leads. What is the magnitude of the current that the wire carries?
