The grid is made up of magnetic and neutral (blackened) plates. Each magnetic plate has two halves: one positive (+) and one negative (−). Halves with the same symbol can not be horizontally or vertically adjacent.
Write a digit from 1 to 9 in each magnetic field, whereby no digit may be repeated in any row or column. The numbers outside indicate the sum of connected numbers, i.e. those not separated by neutral fields, in the correct order. The charges are treated as signs.
Solution code: The marked rows without positive or negative signs, N für neutral fields.

Loved it!
Here's a link to CTC with answer checking enabled too if you want it -- https://sudokupad.app/xf9chyvljt
This one felt like a combination of two of my puzzles -- Japanese sums with Negatives (id=000F1C) and Magnet Sudoku 8x8 (id=000DXS). Magnets is such a sweet genre. Thanks for setting the puzzle!

This was a fantastic puzzle. I was enjoying it thoroughly right up till the moment I made a mistake :-) Couldn't wait to restart and try again. Here's a CTC link if anyone wants to try it online: https://sudokupad.app/v5i3c8lr5r
