The gravitational force on loop is downward. A rectangular loop with dimensions (horizontal=.2m) x (vertical=.46m), is suspended by a string, and the lower horizontal section is immersed in a magnetic field. HOw must the current flow in the loop so that tension in the supporting string is increased? The gravitational force on the loop is downward.

If I understand correctly
F(gravity) = F(magnetic of the loop) + F(magnetic field)

The current must generate a magnetic field in the same direction as the magnetic field below. And the magnetic field below has the same orientation as the gravitational field( downward.. I hope). It will clockwise as if following the right hand screw. The fingers are the direction of current the thumb shows the direction of the generated field.
