There might still be a viable hack:
1. Attach x lines to one single (central) magnet
2. Write x text shapes
3. Drag each text shape ONTO a line so that it becomes a "label"
4. In the lower section of the 'Property: Geometry'-inspector choose 'Parallel' (or 'Perpendicular', whatever effect you are aiming at) to properly align the label's orientation with the line
5. Arrange the lines around the central magnet as you wish
6. Set the color of the lines in the 'Style: Lines & Shape'-inspector to 'white'
(or whatever background color there is)

Here we go...
